The San Mateo County Sheriff's Office has received word from the District Attorney's Office that their investigation into the in-custody death of Kyle V. Harrison has wrapped up, revealing no grounds for criminal charges related to criminal negligence.

Providing details from an earlier report, the Coroner’s Office identified the cause of Harrison's death back in March at the Maple Street Correctional Facility as the toxic effects of three medications, specifically Methadone, Amitriptyline, and Gabapentin, stating the manner of death was "accident." County officials were alerted to these findings after the death of 25-year-old Harrison. The San Mateo County Coroner's Office's independent report noted that these medications ingested in a lethal combination caused Harrison's untimely passing, but no criminal charges would be pursued.

On March 15, personnel at the Maple Street Correctional Center found Harrison unresponsive, and despite immediate life-saving efforts by both Sheriff's Office staff and medical personnel stationed at the facility, he was pronounced dead within its walls. This sequence of events led to simultaneous independent investigations by the District Attorney’s Office, the Coroner’s Office, and the Sheriff’s Detectives to unravel the circumstances of the death.

According to the San Mateo County Sheriff’s Office, they are awaiting the findings from the District Attorney’s Office, which have now concluded without charges. In keeping with established procedures, they will update the public when the investigation is fully closed, which presumably leaves this case to rest, barring future developments that might arise.
