PHOENIX (January 31, 2013)--A body found Thursday in some bushes in a Phoenix suburb was positively identified as Arthur Douglas Harmon, 70, the man who killed a company CEO and critically wounded a lawyer.

A landscaper in Mesa found the body early Thursday morning, one day after the shooting at a north-central Phoenix office building.

Authorities say the rental car Harmon was driving was found nearby in a parking lot.

Police say Harmon died of a self-inflicted gunshot wound, and a handgun was also found.

The shooting happened at the end of a mediation session over a lawsuit Harmon filed against a company in a contract dispute.
