PHOENIX — A gunman opened fire at a Phoenix office complex on Wednesday, killing one person, wounding two others and setting off a manhunt. Police warned that he was ‘‘armed and dangerous.’’
Authorities identified the suspect as Arthur D. Harmon, who they said opened fire at the end of a mediation session. They identified a man who died hours after the shooting as 48-year-old Steve Singer.
Police say a 43-year-old man was listed in critical condition and a 32-year-old woman suffered non-life threatening injuries.
‘‘We believe the two men were the targets. It was not a random shooting,’’ said Sergeant Tommy Thompson, a Phoenix police spokesman.
Thompson said authorities believe Harmon acted alone and fled the scene in a car after the 10:30 a.m. shooting.
Police did not immediately release the names of the wounded. But a Phoenix law firm, Osborn Maledon, said one of its lawyers, Mark Hummels, was among the wounded. The firm said he ‘‘was representing a client in a mediation’’ when he was shot.
According to court documents, Harmon was scheduled to go to a law office in the same building where the shooting took place for a settlement conference in lawsuit he filed against Fusion Contact Centers LLC.
The company had hired him to refurbish cubicles at two call centers in California, but a contract dispute arose.
Fusion said Harmon was paid nearly $30,000 under the $47,000 contract but asked him to repay much of the money when the company discovered that the cubicles could not be refurbished, according to the documents.
Harmon argued Fusion misled him by telling him to remove and store 206 ‘‘worthless’’ work stations after the mix-up was discovered. Harmon said Fusion then told him that the company decided to use a competitor.
