Overview

• Officers were called around 7:02 p.m. after Deputy Jeremy Lyle handed an infant to a neighbor and reported the child’s mother had been hurt, leading them to find Mari Bonnici dead on a couch and two toddlers in a back bedroom.
• Lyle’s truck was spotted at the Sonoma County Coroner’s Office parking lot around 7:32 p.m., triggering nearly five hours of SWAT and hostage-negotiation efforts before he died by a self-inflicted gunshot at about 2 a.m.
• Authorities identified the shooter as 44-year-old Deputy Jeremy Lyle and the victim as 38-year-old detention specialist Mari Bonnici, noting the separated couple had no prior domestic-violence reports on file.
• The three children—twin toddlers and an infant—escaped physical harm and have been placed in the care of relatives.
• The sheriff’s office has expressed grief over the “unimaginable loss” while Santa Rosa police continue to probe the motive during a spike in local homicides this year.
