A man convicted of trying to kill his former girlfriend was sentenced Monday to 21 years in prison.

Pima County Superior Court Judge Jane Eikleberry sentenced Arturo Quiles for attempted first-degree murder and two counts of aggravated assault.

Quiles, who represented himself at the trial, gave a rambling allocution before sentencing. At times he seemed to express remorse for the shooting, while at other times he claimed to have reasons for committing the crime.

Quiles had argued at the trial that the victim betrayed him, which was why he sought to kill her. He had stalked her.

Sseeing the victim during the trial “only served to remind me that I did what I did for a reason,” he said.

“I find your words absolutely chilling,” Eikleberry said.

The Arizona Daily Star has not identified the victim, who has been left permanently disabled because of the multiple bullet wounds she suffered in the attack.
