Upon deputies' arrival, it was determined a 22-year-old male was deceased. The case was immediately assumed by the Riverside County Sheriff’s Department Overdose Death Investigations and Narcotics Unit (ODIN) as it was determined the decedent, Travis O’Brien (22), was a victim of a Fentanyl Poisoning. The investigation continued and a suspect, Riley Hagar (25), from the city of Cathedral City, was identified as being the suspect responsible for selling the Fentanyl that killed O’Brien

On August 31st, 2022, ODIN personnel located Hagar in the city of Rancho Mirage and took him into custody. Additionally, at the time Hagar was taken into custody he was in possession of a large quantity of narcotics and was currently out on bail for an unrelated charge. Hagar was later booked into the Jon Benoit Detention Center for Murder. This investigation is ongoing and anyone with additional information is encouraged to contact Investigator Hollingsworth at 951-955-1700. As a reminder, the Riverside County Sheriff’s Department wants to remind citizens of the dangers of illicit narcotics many which may contain Fentanyl.
