PHOENIX (AP) -- Police are searching for a 70-year-old man suspected in a Phoenix office shooting that left one dead and two wounded, saying that he is "armed and dangerous."
Police identified the suspect as Arthur D. Harmon.
They identified the man who died hours after the Wednesday morning shooting as 48-year-old Steve Singer. He's the CEO of Fusion Contract Centers Inc.
Police say a 43-year-old man was listed in critical condition along with a 32-year-old woman.
Police didn't release the names of the wounded, but a Phoenix law firm said one of their lawyers was among them. It said Mark Hummels was representing a client in mediation.
The gunfire at the office complex prompted workers to lock the doors to their offices and hide far from the windows.
