Andreys Luis Arias was 17 years old when he was arrested in connection with the stabbing at the Main Library on August 19, 2025.
Court documents show Arias pleaded guilty to one count of aggravated assault with a deadly weapon and one count of domestic violence kidnapping.
Arias was ordered to remain in custody until sentencing October 12.
Court documents showed Arias and the 17-year-old victim got into an argument inside the library around 2:10 p.m., and the two knew each other.
Witnesses said he stabbed her several times with a kitchen knife.
Documents state Arias left the knife when he left the scene, but he later called 911 to turn himself in.
The victim identified Arias as the attacker.
During Arias’ first court appearance, the state claimed the victim had seven stab wounds, including one to her eye. She also suffered a punctured lung. The victim’s prognosis is unknown, including if she will regain her sight.

According to his attorney, Arias has significant ties to Tucson and is from Douglas. He is a senior at Tucson High, and the attorney claimed he is a straight-A student with no prior arrests.

“We tried to use the tissues to stop the bleeding as much as we can,” Chauhan said.
Both Chauhan and Mohan flew into Arizona from India earlier that morning, ready to start their first semester pursuing their Master’s degrees at the university.
13 News also spoke to students who were asked to leave the library after the incident. Many of them said they did not know what was happening until they noticed police cars and officers coming into the library.
Other students said they were not surprised that an incident like this occurred on campus, explaining that violent incidents happen at many college campuses nationwide.
“It’s horrible, but it seems to be the culture of the United States right now,” said student David Kirshbaun. “It’s aggressive, people are aggressive, people are bullies and are mean, and it’s something people are getting used to.”
The university said its Crisis Mobile Team is on site to provide support to those directly impacted, and the incident remains under investigation.
Anyone impacted can visit Campus Health’s Counseling & Psych Services (CAPS) website for more information about services available to them. Students can call 520-621-3334.
