PHOENIX (AP) -- A lawyer wounded in this week's Phoenix office shooting has died.
Mark Hummels had been on life support at a Phoenix hospital after Wednesday morning's shooting that killed a Scottsdale-based company's CEO.
His law firm's publicist, Athia Hardt, says Hummels died Thursday night.
Police say the gunman -- 70-year-old Arthur Douglas Harmon -- was found dead early Thursday in Mesa from an apparent self-inflicted gunshot wound.
They say Harmon opened fire at the end of a mediation session over a lawsuit he filed last April.
A woman also was shot, but her injuries were not life-threatening.
The 43-year-old Hummels worked with the law firm Osborn Maledon and focused on business disputes, real estate litigation and malpractice defense.

PHOENIX (AP) -- Police say a man who was wounded in a shooting incident in Phoenix, AZ has died. The suspect in the shooting is on the loose. Police describe that man as `armed and dangerous.'
Police had surrounded a Phoenix home searching for the man suspected of shooting three people, but say he wasn't there.
SWAT teams and two armored vehicles surrounded the house that's about 7 miles from Wednesday morning's shooting scene. Police served a search warrant to enter the home.
They have not identified the suspected gunman. A Phoenix law firm says one of its lawyers was among the wounded.
The Osborn Maledon firm said Mark Hummels "was representing a client in a mediation" when he was shot.
PHOENIX (AP) -- A gunman opened fire at a Phoenix office building on Wednesday, wounding three people, one of them critically, authorities said. Police were searching for the shooter.
The remaining two victims' injuries were less severe, Sgt. Tommy Thompson said. Police do not believe the shooting was a random act, Thompson said.
Authorities said police believe there was only one shooter.
A SWAT team surrounded a house 7 miles from the shooting scene that police said is connected to the shooting. Officers were talking to someone who was not the suspect, Sgt. Steve Martos said.
The gunfire prompted terrified workers throughout the complex to lock the doors to their offices and hide far from the windows. SWAT officers searched the building.
"Everyone was just scared, honestly, just scared," said Navika Sood, assistant director of nursing at First at Home Health Services who along with her co-workers locked the entrances to their office.
Sood said authorities evacuated the office about 30 minutes after she first heard the popping noises.
The shooting took place on the same day that hearings on legislation to address gun violence were convened in Washington, with former Rep. Gabrielle Giffords testifying for stricter gun controls.
A gunman shot Giffords in the head during a shooting rampage in Tucson in January 2011.
Around 10:30 a.m., the gunman arrived at the office building and got into a dispute with someone, a conflict that escalated to the point where he drew a gun and shot three people, Thompson said.
Vannessa Brogan, who works in sales support at an insurance business in the three-story complex, said she heard a loud bang that she thought at first was from somebody working in or near the building.
She said others at the business thought they heard multiple loud noises. She said people locked themselves in offices until authorities evacuated the complex that houses insurance, medical and law offices.
Becky Neher, who works for a title company in the building, said the two gunshots she heard sounded like two pieces of metal banging against each other.
Watching from her second-story office, she saw people leaving the building.
"Someone yelled, `We have a shooter,'" she said. She saw two victims lying on the ground outside the back side of the building. She said health care workers who have offices in the complex came out to help.
Don Jaksa, a software consultant who works in the building, said he was listening to the radio when he suddenly heard "two pops." He said he didn't think they were gunshots.
"My co-worker goes to the range all the time," he said. "He identified it as gunfire."
His co-worker then locked the door. After five minutes, they left and ran into police and someone carrying a stretcher. The police escorted them back to their office and told them to lock the door again.
They were eventually evacuated, and as he sat on a rock outside the complex, his wife called to make sure he was OK after seeing the shooting on the news.
Workers were later allowed to leave the building. Two hugged each other when they got outside.
"You don't expect this when you come to work," worker Lindsa Rincon said.
