Daisone Bernard Hicks died June 26, 14 days after he was booked in connection with an alleged protection-order violation and alleged car theft. The King County Medical Examiner’s Office determined his cause of death about a month later, the report says.

Hicks was booked June 12 and tested positive for fentanyl and methamphetamine. Jail staff prescribed medication to help manage withdrawal and arranged for him to see a provider for medication-assisted treatment.

Surveillance video reviewed by the county showed Hicks entering a common area at about 10 p.m. on June 26 and talking with other people in the facility. He then crouched over a stool and appeared to inhale an unknown substance from its seat, according to the report. At 10:19 p.m., he was seen sitting and slumping over repeatedly. He was unresponsive about five minutes later.

Officers found Hicks during an inmate check nearly half an hour later and began life-saving measures. Health staff administered Narcan, the opioid-overdose reversal medication, but medics soon pronounced him dead.

The review does not identify how fentanyl entered the jail. A jail spokesperson previously said an internal investigation was examining how drugs got into the facility and that evidence would be shared with other law enforcement agencies.

A state-mandated committee of public health and jail staff reviewed the death and said it found no internal structural factors that contributed to it. The area was fully staffed, the report says. The committee recommended continuing to review technology that could monitor residents’ vital signs in real time.

Hicks had been booked into a King County jail eight times since 2019. The report’s findings underscore the challenges of responding to overdose risk in custody, where people may arrive with substance-use disorders and access to illicit drugs remains a security concern.
