Hanlon was 19 years old and studying media production as a second-year student in CU Boulder’s College of Communication, Media, Design and Information. The university confirmed his identity on November 2, following identification by the Boulder County Coroner’s Office.
The fatal incident occurred in the University Hill neighborhood during Halloween celebrations. According to Boulder police, officers received a shooting report at approximately 11:28 p.m. near the 700 block of Marine Street. Two 19-year-old students sustained gunshot wounds and were taken to a hospital. Hanlon later died from his injuries, while the other student was hospitalized.
Authorities subsequently arrested 18-year-old Omar Perez in connection with the shooting. He faces several serious charges, including first-degree murder and assault. The allegations remain subject to court proceedings, and he is presumed innocent unless proven guilty.
On November 5, members of the university community gathered at Dalton Trumbo Fountain Court for a memorial vigil. Students and attendees honored Hanlon with candles, flowers, and messages of sympathy.
University officials also expressed condolences and made support services available to students and staff affected by the tragedy.
Although details about Hanlon’s early life, personal interests, and family have not been widely shared, his loss has deeply affected the campus community.
His memory will remain with those who knew him and those who came together to honor his life. May his family and friends find comfort during this difficult time.
