A Colorado mail carrier was shot and killed Wednesday, the third deadly incident amid of rash of deadly shootings involving U.S. Postal Service workers in recent days. The Longmont Police Department responded to a shooting just after 12:30 p.m. at Heatherhill Street and Renaissance Driv. Wednesday’s deadly incident comes amid a rash of shootings involving postal workers. Two Memphis, Tenn., post office employees were shot and killed Tuesday by a co-worker who died from a self-inflicted gunshot, authorities said; and last week, a Pittsburgh-area postal worker was fatally shot.

Longmont Dep. Chief Jeff Satur told reporters that the letter carrier in Colorado was on his route when someone wearing all black fired multiple shots; when officers arrived, they found the USPS employee shot in front of neighborhood mailboxes. The employee died at the scene, and authorities did not say if the unidentified worker was targeted.

A male suspect wearing all black clothing and a blue mask was seen fleeing the scene on foot, Police Chief Satur said. He said investigators are following up on leads in the case, but declined to say what kind of weapon was used.
