A “cold-blooded” Colorado woman who stood trial for ambushing and killing her ex-boyfriend, a USPS worker, as the victim delivered mail in 2021 was convicted of murder on Tuesday in Boulder County.

Jurors determined that Devan Schreiner, now 27, shot Jason Schaefer, 33, multiple times and committed first-degree murder.
