October 17, 2026 – Placer County Sheriff’s Office officials report that just after 7:00 a.m. on Friday, Placer County Sheriff’s Office K9 Sonic was shot by an armed woman barricaded inside a home on Quarry Lane in Penryn. K9 Sonic was rushed to a veterinary hospital for treatment. During an exchange of gunfire, the woman, 30-year-old Linda Mullennix was struck.

Late Thursday evening detectives attempted to serve an arrest warrant for resisting/obstructing a peace officer (148 PC) and an eviction order signed by a judge on Mullennix. Mullennix also has a history of threatening neighbors, was known to be in possession of a gun, and has been the subject of multiple calls for service. Due to her known history, we attempted to contact and negotiate a peaceful resolution with her outside. When a detective tried to speak with her she ran inside. She then pointed a gun at the detective from a window inside the home and threatened to shoot him. Mullennix then barricaded herself inside and refused to come out.

Several deputies responded and attempted to get Mullinnex to surrender. Just after midnight, the Sheriff’s Office Special Enforcement Team arrived, along with members of the Crisis Negotiation Team. Teams spent several hours attempting to get the woman to come outside and surrender. A number of tactics were attempted including the use of interior drones, contact through the crisis negotiation team via cell phone and a throw-phone, tear gas, the Sacramento County Sheriff’s Office Rook, and non-lethal 40mm rounds.

Mullinnex destroyed multiple law enforcement drones throughout the night.

The Special Enforcement Team made entry into the house, the suspect engaged in gunfire and an officer-involved shooting occurred. K9 Sonic was shot by the suspect. The suspect was also hit and taken to the hospital. No deputies were injured.

Residents in the surrounding area were sent shelter-in-place notifications as deputies continued working to resolve the situation throughout the night.

The Placer County Sheriff’s Office is now following deputy-involved shooting protocols in conjunction with the Placer County District Attorney’s Office.

We ask our community to join us in praying for our K9 officer and his handler. He is in excellent hands at Loomis Basin Veterinary. He was hit in the leg and is expected to recover.
