PHOENIX – A man who shot and killed a call-center CEO and critically wounded a lawyer at a Phoenix office building where they were meeting to discuss a contract dispute was found dead early Thursday, ending a nearly 24-hour manhunt that had area residents on edge.

A landscaper found the body of Arthur Douglas Harmon among some bushes in the Phoenix suburb of Mesa. Harmon, 70, died of an apparent self-inflicted gunshot wound, police said.

A handgun was found near his body, and a rented Kia Optima sedan that he drove from Wednesday's shooting scene was located in a nearby parking lot.
