A Pima County judge sentenced Andreys Luis Arias to 12 years for the UA library stabbing.

A plea and a prison term are the conviction and the sentence on the counts he admitted. They are not a jury trial verdict on attempted murder. KOLD reported prosecutors described a planned attack. Judge Constant called it classic domestic-violence coercive control. The sentence is 12 years plus seven years of probation. It is the judgment.

KOLD reported Monday, Oct. 12, 2026, that Andreys Luis Arias, who was 17 when he was arrested and is now 18, will spend more than a decade in prison after admitting he stabbed his then-girlfriend, Aaniya Coley, at the University of Arizona Main Library on Aug. 19, 2025. KVOA reported Judge Danielle Constant sentenced him to nearly 12 years in prison followed by seven years of probation, and that he pleaded guilty this summer to felony aggravated assault and kidnapping charges. KOLD named the counts as aggravated assault with a deadly weapon and domestic violence kidnapping. KVOA reported he will receive credit for 63 days served as part of the 12-year sentence. A plea is a conviction on the counts admitted. Monday's hearing imposed the term.

KOLD reported prosecutor John Strader told the judge Arias intentionally brought Coley to an isolated location and planned the attack, and that she suffered nine stab wounds to her back, two to her chest, and multiple cuts to her face as Arias followed and attacked her from behind while she tried to escape. KVOA reported Constant cited text messages, internet search history, and his selection of the location, and quoted her saying he brought a knife and a Taser, did not use the Taser, and repeatedly stabbed the victim. KVOA reported both were minors at the time of the attack and had been dating about three years. Prosecutors previously said she suffered a punctured lung and was stabbed in the eye, KVOA reported. Those are the injuries and planning allegations as the stations summarized the hearing and earlier filings.

KOLD reported Constant said she had never seen a clearer example of premeditation in a violent case, considered his age and other mitigating factors, and still called it classic domestic violence. KVOA quoted her: "You needed to control everything and when she wasn't being controlled, you could not take it." KOLD reported Arias apologized in court and said he wished he could take it back. KVOA reported he said he hoped his former girlfriend could eventually forgive him. A defendant's apology is advocacy at sentencing. It is not the judgment. Coley and her family were present, KOLD reported. Naming her is how KOLD and KVOA identified the adult survivor at the sentencing hearing. She is not pictured here.

Twelve years in prison and seven years of probation are the sentence Judge Constant imposed on the plea counts. They are not a finding on a charge he did not plead to. All defendants are presumed innocent until proven guilty in a court of law.
