A 22-year-old Sonoma County sheriff’s correctional deputy has died after falling from a horse while off-duty near Santa Rosa, according to the Sheriff’s Office.

Kylee Johnson was pronounced dead after authorities responded at about 6:50 p.m. Thursday to a medical aid call in the 4000 block of Taylor Avenue south of Santa Rosa. Sheriff’s officials said they have yet to determine whether the fall from the horse caused her death or if it was preceded by a medical emergency.

Johnson’s body was escorted to the county coroner’s office in a procession of patrol vehicles. An autopsy will be conducted to determine her cause of death.

The Sonoma County Sheriff’s Office wrote Friday on social media, “This tragic loss is felt deeply by the Sheriff’s Office, Correctional Deputy Johnson’s loved ones, and the entire Sonoma County community. We ask for your compassion, patience, and support as we grieve together. Please keep her family, friends, and colleagues in your thoughts during this difficult time.”
