How DNA Solved Susan Gale Poole’s 48-Year Mystery

WEBVTT
00:00:00.029 --> 00:00:02.250
My name is Thomas… and this is Human Wreckage.
00:00:02.418 --> 00:00:07.817
Tonight, we begin with a woman whose life quietly vanished into the cracks of America’s forgotten highways.
00:00:07.887 --> 00:00:16.737
Her name was Susan Gale Poole—and for decades, no one could say with certainty where she went, who took her, or how a young woman could simply disappear without leaving a trail behind.
00:00:16.981 --> 00:00:18.251
Susan wasn’t famous.
00:00:18.310 --> 00:00:19.411
She wasn’t wealthy.
00:00:19.460 --> 00:00:21.560
She didn’t live a life that would make headlines.
00:00:21.600 --> 00:00:25.920
And that, tragically, may be the very reason her story slipped through the cracks.
00:00:25.990 --> 00:00:33.100
She was a young woman with dreams that stretched beyond the town she was born in, with hopes of building something more than what fate had handed her.
00:00:33.301 --> 00:00:44.191
Like so many people in the late 1970s and early 1980s, she drifted from place to place, chasing stability, chasing love, chasing the promise that tomorrow would finally be better than yesterday.
00:00:44.503 --> 00:00:47.762
But on the day Susan vanished, that promise was violently stolen.
00:00:48.042 --> 00:00:49.551
There was no dramatic crime scene.
00:00:49.712 --> 00:00:50.292
No blood.
00:00:50.491 --> 00:00:51.572
No broken glass.
00:00:51.752 --> 00:00:52.991
No screaming witnesses.
00:00:53.201 --> 00:00:56.991
Just a woman who never came home—and a family who never stopped waiting.
00:00:57.243 --> 00:01:05.623
As days turned into months… and months into years… Susan Gale Poole became another missing person file buried beneath thousands of others.
00:01:05.793 --> 00:01:08.153
A name typed on aging paperwork.
00:01:08.353 --> 00:01:11.114
A black-and-white photo tucked inside a dusty folder.
00:01:11.384 --> 00:01:13.293
A life reduced to a question mark.
00:01:13.563 --> 00:01:14.593
What happened to Susan?
00:01:14.772 --> 00:01:15.882
Did she leave on her own?
00:01:16.138 --> 00:01:17.909
Was she running from something—or someone?
00:01:18.141 --> 00:01:22.852
Or did she cross paths with someone who saw her not as a human being… but as an opportunity?
00:01:23.075 --> 00:01:25.215
This case isn’t just about a disappearance.
00:01:25.275 --> 00:01:28.724
It’s about how easily a person can be erased when no one is watching.
00:01:28.805 --> 00:01:36.165
It’s about how predators rely on isolation, on vulnerability, and on the belief that no one will notice when someone like Susan is gone.
00:01:36.319 --> 00:01:39.030
Tonight, we’re going to pull Susan’s story out of the shadows.
00:01:39.060 --> 00:01:41.409
We’ll follow the fragments of her last known days.
00:01:41.459 --> 00:01:43.120
We’ll examine the people she trusted.
00:01:43.159 --> 00:01:48.049
And we’ll look closely at the dark possibilities that law enforcement once whispered—but never proved.
00:01:48.198 --> 00:01:53.618
Because behind every cold case file is a real person who laughed, who cried, who loved, and who mattered.
00:01:53.853 --> 00:01:55.073
Susan Gale Poole mattered.
00:01:55.246 --> 00:01:58.027
And on Human Wreckage, we refuse to let her be forgotten.
00:01:58.311 --> 00:02:01.742
A 15-year-old girl vanished from her friend's apartment in Florida.
00:02:01.802 --> 00:02:03.542
Her clothes and purse were still there.
00:02:03.641 --> 00:02:09.611
In June 1974, her skeletal remains were found bound with wire to a tree in a mangrove swamp.
00:02:09.701 --> 00:02:12.322
For 48 years, no one knew who she was.
00:02:12.421 --> 00:02:18.192
Then DNA revealed the truth—and connected her to a serial killer cop who had been dead for 27 years.
00:02:18.292 --> 00:02:19.681
December 1972.
00:02:19.912 --> 00:02:21.012
Broward County, Florida.
00:02:21.247 --> 00:02:24.067
Fifteen-year-old Susan Poole was living between two worlds.
00:02:24.271 --> 00:02:26.512
Her family's trailer park near Fort Lauderdale.
00:02:26.622 --> 00:02:28.171
And a friend's apartment nearby.
00:02:28.406 --> 00:02:29.686
She was a high school dropout.
00:02:29.966 --> 00:02:34.355
A teenager who sometimes skipped class, sometimes hitchhiked, sometimes stayed out late.
00:02:34.645 --> 00:02:37.286
But she wasn't someone who would disappear without a trace.
00:02:37.414 --> 00:02:41.414
Just before Christmas 1972, Susan vanished from her friend's apartment.
00:02:41.604 --> 00:02:42.824
Her clothes were still there.
00:02:42.864 --> 00:02:44.473
Her pocketbook was still on the couch.
00:02:44.806 --> 00:02:48.836
"I knew something was wrong when I saw her purse," her sister Patti would say decades later.
00:02:49.040 --> 00:02:50.080
Susan Poole was gone.
00:02:50.414 --> 00:02:53.585
"Nobody knew where she went," Detective Bill Springer would later explain.
00:02:53.724 --> 00:03:02.094
Her family reported her missing, but in 1972, teenagers like Susan—troubled, independent, known to run away for a day or two—didn't always get the attention they deserved.
00:03:02.213 --> 00:03:03.574
Police assumed she'd come back.
00:03:03.823 --> 00:03:04.522
Days passed.
00:03:04.552 --> 00:03:05.062
Then weeks.
00:03:05.152 --> 00:03:05.752
Then months.
00:03:05.929 --> 00:03:06.938
Susan never came home.
00:03:07.182 --> 00:03:09.013
June 16, 1974.
00:03:09.013 --> 00:03:10.122
Palm Beach County, Florida.
00:03:10.304 --> 00:03:16.443
A man and his sons were searching for driftwood in a remote, swampy area called Burnt Bridges along Highway A1A.
00:03:16.563 --> 00:03:18.294
Instead, they found something horrific.
00:03:18.344 --> 00:03:19.275
Human remains.
00:03:19.375 --> 00:03:20.224
Scattered bones.
00:03:20.335 --> 00:03:21.245
Scraps of clothing.
00:03:21.439 --> 00:03:24.080
And a skeleton bound with wire to a mangrove tree.
00:03:24.210 --> 00:03:30.090
"She was tied up in the mangroves with wire to a tree," Detective Springer would say nearly 50 years later.
00:03:30.169 --> 00:03:36.532
"She was skeletal remains, totally nothing left of her except bones." Investigators tried everything to identify her.
00:03:36.752 --> 00:03:38.562
They created composite sketches.
00:03:38.711 --> 00:03:40.551
They searched missing persons reports.
00:03:40.752 --> 00:03:42.572
They waited for someone to recognize her.
00:03:42.801 --> 00:03:43.431
No one did.
00:03:43.611 --> 00:03:47.141
In 1974, they didn't have the DNA technology that exists today.
00:03:47.211 --> 00:03:49.102
The case went cold almost immediately.
00:03:49.389 --> 00:03:50.719
The girl remained nameless.
00:03:50.889 --> 00:03:51.469
A ghost.
00:03:51.729 --> 00:03:53.270
A question mark in the mangroves.
00:03:53.502 --> 00:03:56.432
For nearly 48 years, she was known only as Jane Doe.
00:03:56.687 --> 00:04:01.228
In 2015, investigators submitted DNA to a national missing persons database.
00:04:01.578 --> 00:04:02.008
Nothing.
00:04:02.270 --> 00:04:05.131
In 2019, they prepared a new facial reconstruction.
00:04:05.341 --> 00:04:06.350
No one recognized her.
00:04:06.692 --> 00:04:07.882
The case seemed hopeless.
00:04:07.921 --> 00:04:12.842
Whoever she was, whatever had happened to her, the answers had been buried with her bones in 1974.
00:04:13.008 --> 00:04:21.588
And then, in December 2021, the Palm Beach County Sheriff's Office sent the skeletal remains to Othram—a Texas forensics lab specializing in genetic genealogy.
00:04:21.689 --> 00:04:23.918
Othram built a comprehensive DNA profile.
00:04:24.028 --> 00:04:28.798
In March 2022, their genealogy team returned investigative leads to the sheriff's office.
00:04:28.901 --> 00:04:30.321
Detectives followed the leads.
00:04:30.461 --> 00:04:32.451
They contacted potential family members.
00:04:32.672 --> 00:04:33.971
They found Susan Poole's mother.
00:04:34.002 --> 00:04:35.052
She was in her 90s.
00:04:35.091 --> 00:04:37.971
She had been waiting 50 years for answers about her daughter.
00:04:38.278 --> 00:04:40.639
Investigators collected a DNA sample from her.
00:04:40.908 --> 00:04:41.629
It was a match.
00:04:41.884 --> 00:04:43.134
June 2, 2022.
00:04:43.134 --> 00:04:44.624
Palm Beach County Sheriff's Office.
00:04:44.855 --> 00:04:49.886
Detective Bill Springer stood before reporters and announced what the family had waited half a century to hear.
00:04:50.226 --> 00:04:54.216
The girl found bound to a tree in 1974 was Susan Gale Poole.
00:04:54.547 --> 00:04:57.007
Born February 12, 1957.
00:04:57.247 --> 00:05:00.997
Fifteen years old when she disappeared just before Christmas 1972.
00:05:01.319 --> 00:05:03.709
"The family was happy to know what happened," Springer said.
00:05:04.038 --> 00:05:08.182
"It's been a long time waiting to see what happened to their sister." But the story didn't end there.
00:05:08.456 --> 00:05:10.476
Because Springer believed he knew who killed her.
00:05:10.733 --> 00:05:11.853
Gerard John Schaefer.
00:05:12.105 --> 00:05:13.446
A former sheriff's deputy.
00:05:13.636 --> 00:05:14.855
A former police officer.
00:05:15.026 --> 00:05:17.115
A man who used his badge to hunt young women.
00:05:17.391 --> 00:05:19.821
A serial killer who had been dead for 27 years.
00:05:20.093 --> 00:05:26.673
In 1972—the same year Susan Poole disappeared—Gerard Schaefer was working as a deputy for the Martin County Sheriff's Office.
00:05:26.827 --> 00:05:28.148
He was 26 years old.
00:05:28.358 --> 00:05:29.158
He had a badge.
00:05:29.307 --> 00:05:30.338
He had a patrol car.
00:05:30.458 --> 00:05:31.298
He had authority.
00:05:31.517 --> 00:05:33.468
And he used all of it to prey on young women.
00:05:33.721 --> 00:05:34.781
July 1972.
00:05:34.990 --> 00:05:36.680
Five months before Susan disappeared.
00:05:36.961 --> 00:05:45.521
Two teenage girls—Nancy Trotter, 18, and Paula Sue Wells, 17—were hitchhiking near the beach when they encountered an on-duty sheriff's deputy.
00:05:45.605 --> 00:05:46.475
Gerard Schaefer.
00:05:46.713 --> 00:05:48.314
He told them hitchhiking was illegal.
00:05:48.564 --> 00:05:49.004
It wasn't.
00:05:49.331 --> 00:05:55.922
"He called into the station on his radio and said he had two girls and asked if it was okay to take us home," Trotter later told reporters.
00:05:56.101 --> 00:06:01.435
"They said to him,'OK,' so we got in the back seat of the police car." But Schaefer didn't take them home.
00:06:01.704 --> 00:06:03.543
He drove them to a remote wooded area.
00:06:03.574 --> 00:06:04.744
He tied them to trees.
00:06:04.774 --> 00:06:06.324
He put nooses around their necks.
00:06:06.353 --> 00:06:07.684
He told them he'd be back later.
00:06:07.863 --> 00:06:08.473
Then he left.
00:06:08.908 --> 00:06:10.149
The girls managed to escape.
00:06:10.189 --> 00:06:11.499
They reported him immediately.
00:06:11.704 --> 00:06:15.264
Schaefer was arrested and charged with aggravated assault and false imprisonment.
00:06:15.459 --> 00:06:17.379
He was released on$15,000 bail.
00:06:17.509 --> 00:06:19.519
September 27, 1972.
00:06:19.660 --> 00:06:20.540
Fort Lauderdale.
00:06:20.701 --> 00:06:22.661
While out on bail, Schaefer struck again.
00:06:22.874 --> 00:06:26.233
Two more teenage girls: Susan Place, 17, and Georgia Jessup, 16.
00:06:26.439 --> 00:06:32.415
They told Place's mother they were going to the beach with an older man named"Gerry Shepherd." Place's mother was suspicious.
00:06:32.444 --> 00:06:35.264
She wrote down the license plate number of his blue-green Datsun.
00:06:35.612 --> 00:06:37.302
The girls were never seen alive again.
00:06:37.526 --> 00:06:38.886
April 1, 1973.
00:06:38.886 --> 00:06:39.766
Hutchinson Island.
00:06:39.980 --> 00:06:46.040
A father and son were searching for aluminum cans when they found decomposed, mutilated, decapitated remains in the woods.
00:06:46.192 --> 00:06:46.802
Susan Place.
00:06:46.833 --> 00:06:47.512
Georgia Jessup.
00:06:47.653 --> 00:06:50.103
The license plate led investigators to Gerard Schaefer.
00:06:50.283 --> 00:07:10.072
When they searched a trunk stored at Schaefer's mother's home in Fort Lauderdale, they found: The victims' jewelry Human teeth Women's clothing A passport Personal effects belonging to at least six missing females Approximately 50 pages of handwritten notes graphically describing murders, torture, and mutilation Schaefer was arrested and charged with two counts of first-degree murder.
00:07:10.305 --> 00:07:12.685
In October 1973, he was convicted.
00:07:12.725 --> 00:07:13.625
Two life sentences.
00:07:13.732 --> 00:07:16.451
Authorities suspected he was connected to up to 30 murders.
00:07:16.622 --> 00:07:18.271
But he was only convicted of two.
00:07:18.423 --> 00:07:23.733
Robert Stone, the prosecutor who convicted Schaefer, called him"the most sexually deviant person I had ever seen.
00:07:23.833 --> 00:07:35.480
He made Ted Bundy look like a Boy Scout." Schaefer became known as the"Killer Cop," the"Hangman," and the"Butcher of Blind Creek." His method was consistent: lure young women—often hitchhikers—using his badge.
00:07:35.550 --> 00:07:38.271
Drive them to remote areas along Highway A1A.
00:07:38.341 --> 00:07:40.321
Tie them to trees with wire or rope.
00:07:40.360 --> 00:07:41.661
Put nooses around their necks.
00:07:41.690 --> 00:07:42.240
Torture them.
00:07:42.240 --> 00:07:42.771
Kill them.
00:07:42.963 --> 00:07:50.069
The tree where he killed his victims became known in South Florida as the"Devil Tree." While in prison, Schaefer maintained his innocence publicly.
00:07:50.403 --> 00:07:56.543
But privately, in letters to his former high school girlfriend Sondra London, he boasted of killing more than 30 women and girls.
00:07:56.689 --> 00:08:04.608
He wrote graphic"killer fiction" stories—detailed accounts of torture and murder that investigators believed were confessions disguised as fiction.
00:08:04.815 --> 00:08:08.276
He filed frivolous lawsuits against anyone who called him a serial killer.
00:08:08.651 --> 00:08:11.060
And he waited for parole, scheduled for 2016.
00:08:11.348 --> 00:08:12.858
December 3, 1995.
00:08:12.858 --> 00:08:13.767
Florida State Prison.
00:08:13.887 --> 00:08:15.927
Gerard Schaefer was found dead in his cell.
00:08:16.168 --> 00:08:20.257
He had been stabbed over 40 times—in the face, head, neck, and body.
00:08:20.408 --> 00:08:21.627
His throat was slashed.
00:08:21.697 --> 00:08:23.057
His right eye was destroyed.
00:08:23.137 --> 00:08:24.478
Several ribs were fractured.
00:08:24.709 --> 00:08:28.668
Fellow inmate Vincent Rivera was convicted of the murder in 1999.
00:08:28.889 --> 00:08:30.738
Schaefer died at age 49.
00:08:30.978 --> 00:08:33.249
He never revealed the full extent of his crimes.
00:08:33.278 --> 00:08:36.428
Families of missing women lost their last chance for answers.
00:08:36.610 --> 00:08:37.301
Or so they thought.
00:08:37.503 --> 00:08:43.003
When Detective Springer identified Susan Poole's remains in 2022, he immediately suspected Gerard Schaefer.
00:08:43.335 --> 00:09:15.072
The evidence was circumstantial but compelling: Susan disappeared in December 1972—just three months after Schaefer killed Place and Jessup She was found in Palm Beach County, along Highway A1A—Schaefer's hunting ground She was bound with wire to a tree—Schaefer's signature method She was known to hitchhike—Schaefer's preferred targets Schaefer lived in Broward County, where Susan lived"Because of the similar way in which those teens were killed," Springer said,"I believe Schaefer could have been involved in Poole's death." But Schaefer had been dead for 27 years.
00:09:15.142 --> 00:09:16.341
There would be no confession.
00:09:16.422 --> 00:09:17.111
No trial.
00:09:17.182 --> 00:09:18.282
No definitive proof.
00:09:18.376 --> 00:09:20.086
Only suspicion, method, and timing.
00:09:20.298 --> 00:09:22.128
Springer is still looking for evidence.
00:09:22.158 --> 00:09:25.898
He's trying to reach three of Susan's friends who lived near her in 1972.
00:09:26.241 --> 00:09:30.822
"The three could help us find the missing piece and give her family closure," the sheriff's office said.
00:09:30.979 --> 00:09:35.019
Springer wants to know: Did Susan ever mention knowing someone named Gerard?
00:09:35.078 --> 00:09:38.749
Did she confide in anyone about a relationship with a police officer?
00:09:38.839 --> 00:09:41.589
Did she frequently hitchhike along Highway A1A?
00:09:41.775 --> 00:09:43.285
The answers might still be out there.
00:09:43.465 --> 00:09:45.115
December 1972.
00:09:45.225 --> 00:09:49.304
Susan Poole, 15, vanished from her friend's apartment in Florida.
00:09:49.394 --> 00:09:51.414
Her clothes and purse were left behind.
00:09:51.485 --> 00:09:57.115
In June 1974, her skeletal remains were found bound with wire to a mangrove tree.
00:09:57.174 --> 00:09:59.705
For 48 years, no one knew who she was.
00:09:59.784 --> 00:10:04.304
Then, in 2022, DNA matched her to her 90-year-old mother.
00:10:04.485 --> 00:10:13.345
Investigators now believe Susan was a victim of Gerard Schaefer—a serial killer sheriff's deputy who was convicted of two murders but suspected of killing 30.
00:10:13.495 --> 00:10:15.835
Schaefer died in prison in 1995.
00:10:15.955 --> 00:10:17.134
He never confessed.
00:10:17.215 --> 00:10:21.024
But 27 years after his death, Susan's bones finally spoke.
00:10:21.174 --> 00:10:24.995
And after half a century of silence, her family finally knows what happened.
00:10:25.128 --> 00:10:28.408
Susan Gale Poole did not disappear because she was invisible.
00:10:28.567 --> 00:10:32.518
She disappeared because the world, for a moment, failed to look closely enough.
00:10:32.736 --> 00:10:36.067
When someone like Susan vanishes, there’s no final chapter.
00:10:36.256 --> 00:10:37.817
There is no courtroom verdict.
00:10:37.876 --> 00:10:38.986
No grave to visit.
00:10:39.167 --> 00:10:43.206
Only unanswered questions that echo through the lives of those who loved her.
00:10:43.427 --> 00:10:51.677
Somewhere, a truth still exists locked inside memories, buried in forgotten places, or held by someone who has stayed silent for far too long.
00:10:51.823 --> 00:10:54.813
Cases like Susan’s don’t go cold because the victims stop mattering.
00:10:54.894 --> 00:10:58.774
They go cold because time moves on… and people grow comfortable with uncertainty.
00:10:58.894 --> 00:11:00.543
But uncertainty is not justice.
00:11:00.634 --> 00:11:02.053
And silence is not closure.
00:11:02.279 --> 00:11:08.549
If Susan’s story has taught us anything, it’s that predators thrive in the shadows and those shadows grow deeper when no one speaks.
00:11:08.629 --> 00:11:10.080
Someone out there knows something.
00:11:10.159 --> 00:11:10.679
A name.
00:11:10.769 --> 00:11:11.320
A place.
00:11:11.409 --> 00:11:13.049
A moment that never quite sat right.
00:11:13.190 --> 00:11:15.590
A detail that has been carried quietly for years.
00:11:15.730 --> 00:11:19.971
Even the smallest piece of information can be the crack that lets the truth finally break through.
00:11:20.142 --> 00:11:23.392
Susan Gale Poole was more than a missing woman on a faded poster.
00:11:23.552 --> 00:11:24.402
She was a daughter.
00:11:24.611 --> 00:11:25.172
A friend.
00:11:25.331 --> 00:11:29.831
A human being whose life did not end the moment she vanished it was simply interrupted.
00:11:30.110 --> 00:11:32.640
And until the truth is known, her story remains unfinished.
00:11:32.913 --> 00:11:42.352
If you have any information about the disappearance of Susan Gale Poole, no matter how insignificant it may seem, we urge you to contact your local authorities or the appropriate cold case investigators.
00:11:42.482 --> 00:11:45.322
Justice doesn’t always come quickly… but it can still come.
00:11:45.499 --> 00:11:46.479
My name is Thomas.
00:11:46.623 --> 00:11:47.993
And this has been Human Wreckage.
