A man who shot and killed a call-centre 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.

Authorities had been searching for Harmon since Wednesday morning, when they say he drew a gun and shot two men at the end of a mediation session at a north-central Phoenix office building.

Steve Singer, 48, died hours later. The law firm that employs Mark Hummels, 43, said Thursday he is on life support and isn't expected to survive.

A third person, 32-year-old Nichole Hampton, was caught in the gunfire near the office building's entrance and suffered a gunshot wound to her left hand. The mother of two is recovering and expects to be discharged from a hospital Friday.
