On July 27, 2010, at approximately 1855 hrs. the Ventura County Sheriff’s Department received a call from the California Highway Patrol requesting mutual aid. A CHP officer had been dispatched to a vehicle vs. pedestrian traffic collision near the 1100 block East Guiberson Rd. in the unincorporated area of Fillmore.

The suspect, Cheree Sanker, attempted to run over Juan Gonzales and Yesemia Zavala as they were walking along the side of Guiberson Rd. Zavala called 9-1-1 on her cell phone, and notified CHP of the incident.

As the first CHP unit arrived on scene, Sanker, attempted to ram the CHP unit head-on. CHP officer Mumme was able to avoid a head on collision, but Sanker’s vehicle collided with the right rear side of the unit.

CHP officer Mumme was able to exit his unit while Sanker was still inside of her vehicle holding a knife, threatening to take her own life. Additional Officers from the CHP and the Sheriff’s Department arrived and after a short time Sanker was convinced to discard the knife and surrender to officers.

AMR Ambulance transported CHP officer Mumme to a local hospital with a complaint of pain to his abdomen. Sanker was transported to the Ventura County Medical Center and admitted for observation. Sanker was booked on charges of 245 (a)(1) P.C. Assault with a Deadly Weapon.
