After a jogger's body was found in a Philadelphia park, police told runners to be on their guard—but it seems the murder wasn't an arbitrary killing. Instead, police say Christopher Murray, husband of jogger Constance Murray, killed his wife in an argument, the AP reports. Murray confessed to the crime after failing a lie detector test, police say, per the Philadelphia Daily News. "I think it was more of a rage incident ... than premeditated," officer Philip Riehl says.
Amid "some ongoing domestic discord," Murray allegedly jumped in a car and followed his wife when she went jogging; at that point, police say, they don't think he was planning to kill her, Reuters notes. The couple ended up arguing on a bench. "She went up there voluntarily to talk to him about whatever was going on and things went bad," the officer notes. Police say Christopher Murray strangled Constance and left her body nearby; he later reported her missing, the AP notes. "The reality was he became a suspect early on and remained a suspect until he confessed," Riehl says, adding that "the people [who] play and exercise in the area … can have a sigh of relief because there is not a predator lurking." The couple has two daughters, ages 12 and 15, per the Daily News.
