A Colorado woman will spend the rest of her life behind bars for killing her United States Postal Services former boyfriend while he was on his route.

On Oct. 13, 2021, Jason Schaefer was delivering mail in Longmont when a woman approached him, fired multiple shots and killed him before running off.

Police were able to identify the suspect wearing a hooded sweatshirt and mask as the victim’s 26-year-old ex-girlfriend, Devan Schreiner, and she was arrested for first-degree murder.

On March 7, a jury convicted Schreiner of the charge against her, KCNC-TV reported.

She received a sentence of life in prison without the possibility of parole.


“This defendant is a cold-blooded murderer,” District Attorney Michael Dougherty said of the defendant.

“She took steps to get away with this brutal murder, but she underestimated two things,” he continued. “First, the victim was very much loved by his family and co-workers; the information and support they provided was critical. Also, the US Postal Inspectors and Longmont detectives brought their best efforts and, along with our prosecution team, ensured justice was done. As always, we appreciate the time and service of the jurors.”
