Summary

On October 13th, 2021, 33-year-old postal worker Jason Schaefer was fatally shot five times on his route in Longmont, Colorado. Initial investigations ruled out robbery, focusing on a targeted attack. Detectives interviewed Jason's girlfriend, Rosa, who revealed a volatile history with Jason's ex-girlfriend and mother of his son, Devon Shriner. Rosa, who is also Devon's sister, suspected Devon, citing her anger over Jason dating her and his recent filing for increased custody. Surveillance footage placed a black Nissan Rogue, registered to Devon, near the crime scene. GPS data from Devon's postal scanner showed it stationary during the shooting, contradicting her alibi of being on her route. When confronted, Devon denied involvement and requested a lawyer. Further investigation implicated Devon's boyfriend, AJ Richie, a correctional officer with access to firearms. AJ initially provided a false alibi but later confessed, revealing Devon's long-standing fixation on killing Jason, especially after the custody filing. AJ admitted to acting as a lookout, tracking Jason's movements using a 'Way to Go' ride-share Dodge Durango and relaying information to Devon. Snapchat screenshots from AJ's phone showed Devon in clothing similar to the shooter's just days before the murder. Both Devon Shriner and AJ Richie were found guilty of first-degree murder and sentenced to life in prison without parole, leaving their 6-year-old son without either parent.
This case highlights the critical role of digital forensics, including GPS data from work devices, cell phone records, and surveillance footage, in solving complex murder investigations.
