Phoenix lawyer shot after mediation session dies

A lawyer wounded in an attack at a Phoenix office has died, bringing the toll from this week’s shooting to three, including the gunman.

Mark Hummels, 43, was taken off life support Thursday night, Athia Hardt, a spokeswoman for his law firm told The Los Angeles Times on Friday. Hummels was brain-dead and was an organ donor, said Hardt, who represents the Phoenix law firm Osborn Maledon.

On Wednesday, a gunman attacked Hummels and others after a mediation session to end a lawsuit.

The gunman was identified as Arthur Douglas Harmon, 70, who was found dead early Thursday from an apparent self-inflicted gunshot wound, police said.

Harmon had been hired to renovate some office cubicles in a call center operated by Fusion Contact Centers LLC. The parties clashed over money owed for the work.

After the session, Harmon opened fire, hitting Hummels, his client, Steve Singer, 48, chief executive of Fusion and a female bystander who was slightly wounded in the hand.

Singer died hours later. Hummel was placed on life support until Thursday.

Hummels was a former reporter for the Albuquerque Journal and Santa Fe New Mexican before he went to law school in 2001. He was admitted to the Arizona bar in 2005.
