A female deputy sheriff was hospitalized after being violently attacked by two female inmates at West Valley Detention Center on Nov. 13, according to the San Bernardino County Sheriff's Department.
One additional inmate allegedly participated in the assault, the Sheriff's Department said.
At about 6:12 p.m., the deputy was supervising inmates inside a housing unit. The deputy came across two inmates on the ground in one of the housing segments.
One of the inmates (Kyanna Patterson, 24) appeared to be having a seizure and the other (Rose Villalobos, 32) appeared to be assisting her.
But as the deputy approached them, Villalobos stood up and allegedly threw a cup of vomit onto the deputy’s face. Villalobos continued to assault the deputy and allegedly slashed her face with a razor. Villalobos also allegedly grabbed the deputy’s radio and struck her with it, numerous times to the head.
In addition, Patterson allegedly threw a cup at the deputy, striking her in the chest.
Additional deputies responded to the housing segment and detained the inmates.
The deputy was transported to a local area hospital for treatment of her injuries. She has since been released and is expected to make a full recovery.
During the investigation, it was determined that another inmate, Amber Tena, also allegedly participated in the coordinated assault by alerting the others when to attack as the deputy approached, the Sheriff's Department said.
Upon completion of the investigation, a report will be submitted to the District Attorney’s Office for review and consideration of additional charges.
Villalobos has been in custody since April of 2019 on an assault charge.
Patterson has been in custody since August of 2018 on charges of attempted murder, hit and run with Injury and evading a peace office with disregard to public safety.
Tena was most recently charged with a crime in August of 2019 for prisoner manufacturing a weapon.
