PHOENIX - 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.
