A man died from an apparent drug overdose late Thursday night at the Santa Barbara County Main Jail near Santa Barbara, according to the Sheriff’s Office.

A custody deputy and a WellPath nurse were conducting welfare checks at the jail’s inmate reception center shortly before 11 p.m. when they found a man who did not respond to the check-in procedure, said Lt. Jarrett A. Morris.

“Custody deputies and medical staff entered the cell to physically check the inmate’s condition, and found him unresponsive, not breathing, and with a foamy purge coming from his mouth,” Morris said in a statement.

Deputies and medical personnel administered three rounds of Narcan, performed CPR, and used an automated external defibrillator (AED) — but the man did not recover, Morris said.

The Sheriff’s Office identified him as Rio Favorite Ulvaeus, 45, of Santa Barbara. He had been in custody since Wednesday afternoon.

Detectives from the sheriff’s Criminal Investigation Bureau and the Coroner’s Bureau are investigating the in-custody death.

“Sheriff’s detectives will conduct an extensive investigation into the inmate’s death, but preliminary information indicates this death is likely the result of an opioid overdose,” Morris said.

The Sheriff’s Office issued a statement reminding the community about the immediate dangers posed by the presence of fentanyl, an addictive and dangerous synthetic opioid.

Free Narcan — a powerful tool in the fight against opioid overdoses that has the potential to reverse the fatal effects of fentanyl — is available from the Pacific Pride Foundation, the Santa Barbara Opioid Safety Coalition, UC Santa Barbara Student Health Services Alcohol and Drug Program, and Fentanyl is Forever SB.
