A man matching the description of a spree-killing suspect* in Montgomery County, Pennsylvania attempted to rob a Doylestown Township man who was walking his dog of his car keys.

Doylestown Township Police reported:

Doylestown Township Police is investigating an attempted armed robbery that occurred on 12/15/14 at approximately 7:00PM. The victim was walking his dog in the area of Burpee Road and Shady Retreat Road when he was confronted by a suspect carrying a knife. The suspect described as a w/m approximately 5’10” wearing camouflage clothing demanded his car keys.
The victim resisted and fell to the ground. The victim was armed and fired multiple rounds at the suspect. The suspect was last seen running from the area.

The murderer is believed to have killed his ex-wife and five of her family members. The killer and his wife were locked in a bitter custody battle. His current wife, their infant child and the two children that were at the center of the custody dispute are in police protective custody.

Breaking news suggests that the murderer has been found deceased, presumably by his own hand.

One has to wonder if the killer gave up, psychologically speaking, when he failed to steal the victim’s car keys and felt trapped in the area.

Update: Authorities has now stated that the carjacker could not have been the killer, as the killer appears to have been dead for some time. An investigation into the carjacking claim continues.
