PHOENIX, Ariz. — A second victim of the Phoenix office-complex shooting has died.

Mark Hummels, a lawyer from Greeley, passed away Thursday night. He was taken off life support, according to a statement from his office.

I regret to inform you that our friend, Mark Hummels, died last night,” the statement read. “He was declared brain dead and taken off life support.”

Hummels had undergone surgery at an Arizona hospital for bullet wounds to his neck and back, suffered in Wednesday’s shooting.

He is the second fatality linked to suspected shooter Arthur Douglas Harmon, 70, of Phoenix. Steve Singer, the first victim, died a few hours after the shooting.

Hummels, 43, was representing Singer in a lawsuit filed by Harmon, according to court documents. The victims and the suspect had been at a settlement hearing earlier in the day at the office complex at 16th Street and Glendale Avenue.
