The defendant told the jurors they should convict him, and they agreed.

After less than an hour of deliberation, the jury found Arturo Quiles guilty on all counts of trying to kill his former girlfriend.

“In my opening statement, I said this was a simple case of betrayal and revenge, and it is,” Quiles, 42, said in closing arguments in his trial for attempted first-degree murder. “I also said this would end in your returning a guilty verdict, and that’s exactly what you’re going to do.”

Quiles, who chose to represent himself, was on trial before Pima County Superior Court Judge Jane Eikleberry, accused of attempted first-degree murder and two counts of aggravated assault.

He was accused of staking out his former girlfriend and shooting her as she left her apartment for work. The Arizona Daily Star has not identified the victim to protect her identity.

Deputy Pima County Attorney Rona Kreamer said Quiles was obsessed with thoughts of revenge against the victim after their relationship dissolved.

“He couldn’t get out of his mind these perceived slights,” Kreamer said.

She told jurors the defendant’s own words were proof enough that he committed the act with premeditated intent.

“He said it himself from that stand: ‘I wanted to kill her,’ ” Kreamer said.

She described to the jury how Quiles had stalked the victim and hid out near her front door on the morning of June 4, 2012.

Quiles then shot the victim numerous times. As she lay bleeding on the sidewalk, he shot her several more times in the abdomen.

When it was over, the victim had seven bullet wound in her legs, arms and midsection.

In his closing arguments, Quiles said he originally intended to kill the victim but instead chose to spare her life by not shooting her in the chest.

Quiles is scheduled for sentencing on July 28.
