(UPI) -- Police in Mesa, Ariz., reported finding a man with an apparent self-inflicted gunshot wound who matches the description of a suspect in a Phoenix shooting.
Phoenix police Sgt. Steve Martos said a person matching the description of the suspect, 70-year-old Arthur Douglas Harmon, was found Thursday with what appeared to be a self-inflicted gunshot wound, KTVK-TV, Phoenix, reported.
"Mesa Police have informed us they have located the suspect vehicle involved in yesterday's [Wednesday's] incident," Martos said in an email distributed to media outlets Thursday. "In addition, they have located an individual matching the suspect description nearby with what appears to be a self-inflicted gunshot wound."
Harmon hasn't been seen since he fled the area of the law office shooting, where one person died and two others were injured, soon after it occurred Wednesday, police said.
Police dispatchers Thursday kept broadcasting the description of Harmon's rental vehicle, a white 2013 Kia Optima with Arizona plates, The Arizona Republic in Phoenix reported.
Harmon was reported in a legal battle with a telephone call center. Phoenix Police said they think Harmon targeted two men and shot another person after a mediation session at building in north-central Phoenix.
Killed was Steve Singer, 48, the call center's executive office and a defendant in the lawsuit filed by Harmon. Singer's attorney, Mark Hummels, sustained serious wounds to his neck and back. Bystander Nicole Hampton was shot near the building entrance, suffering a hand wound.
On Thursday, a citizen reported seeing the car in a parking lot and reported it to police, KNXV-TV, Phoenix, said.
