Tucson man convicted in girlfriend's 2012 killing

Posted: Updated:

A Tucson man accused of fatally bludgeoning his girlfriend with a crowbar in 2012 has been convicted of second-degree murder.

Pima County Superior Court jurors convicted 50-year-old Arnold Mills Granillo on Friday in his second trial. His first trial ended last December in a hung jury.

Granillo is scheduled to be sentenced on Oct. 10.

Prosecutors say Granillo beat 45-year-old Kimberly Tsonetokoy over the head, face and body up to a dozen times after she told him of her plans to end their relationship in September 2012.

Granillo's lawyer says his client acted in a passionate rage when he learned Tsonetokoy planned to leave him after they lived together for nearly a decade.

Character witnesses testified that the former Sun Tran bus driver had no history of violence.
