Friendly Postal Worker Murdered While Delivering Mail

In October 2021, Jason Schaefer was delivering mail on his typical mail route in Longmont, CO, when someone walked up to him and shot him in the face. Despite first responders’ best efforts, he was pronounced dead at the scene. By the end of the day, police had arrested someone for his murder. This person was Devan Schreiner. 

Jason and Devan had dated in the past and shared a son but were no longer together. Two days before the murder, Jason had filed for full custody, and investigators soon discovered that Jason had been dating Devan’s sister. Devan had a motive, but police needed hard evidence. Luckily, almost everyone has some sort of camera on their house, and police are able to collect this footage from houses in the area as evidence. As if this wasn’t enough, Devan is also a mail carrier and her mail scanner had been inactive for about an hour during the time of Jason’s murder. 

All of this evidence points to Devan, but detectives were also able to collect enough evidence to implicate Devan’s boyfriend, AJ  Ritchie, in the murder as well. Devan and AJ were tried separately and were both found guilty. 

Come along with Hannah and Lainey as they discuss s’mores, the food groups, and the United States Postal Service.
