It took less than one hour Monday for a Pinal County jury to find Arthur Eric Magaña guilty of killing 20-year-old Wyatt Miller.
Magana was convicted of first-degree murder after shooting Miller 11 times in the back of the head and neck on Nov. 7, 2016. The jury also found Magaña guilty of armed robbery as Miller was killed during the theft of four ounces of marijuana.
Magaña, now 18, is accused of killing Miller inside his truck. The alleged murder took place in a rural area of Maricopa, according to court testimony.
Magaña was just 16 years old at the time of the murder but is charged as an adult due to the gruesome nature of the murder.
Magaña’s murder and armed robbery trial began Wednesday and was handed to the nine-woman, three-man jury Monday afternoon just after 2 p.m. The jury took under an hour to return the guilty verdicts.
The jury was brought back into the courtroom at 3:45 p.m. to hear sentencing instructions and decide Magaña’s fate in the second phase of the trial.
Judge Kevin White said the jury will only determine the aggravated circumstances and not Magaña’s sentence. White will be the one to determine the 18-year-old’s sentence.
The state called two witnesses in the second phase of the trial including Maxine Medlock, Wyatt Miller’s mother.
“I’m not sure where to begin. Wyatt was the love of my life. He had such a good spirit. A loss of a child is so painful. The pain never goes away. Wyatt had his whole life ahead of him… I’m upset I have to live the rest of my life without him,” she said.
The state also called Travis Miller, Wyatt’s father. “We, as parents, aren’t supposed to bury our children,” he said. “My life has changed 180 degrees.”
The defense called no witnesses in the second phase.
The jury left the courtroom at 4:15 to determine if the first-degree murder charge would be enhanced due to aggravating circumstances. Attorneys were told to wait in the hallway as the jury decided.
The jury returned at 4:46 to hand down their aggravating circumstances endorsement.
Magana’s fate then rested in the hands of Judge White. He ordered Magaña held without bond and set sentencing for Dec. 17.
