Mule Creek State Prison

Mule Creek State Prison is located in the city of Plymouth, California which has a population of 979 (as of 2013) residents. This prison has a capacity of 1,700 inmates, which means this is the maximum amount of beds per facility. Mule Creek State Prison began processing inmates once the original construction was completed and service started in 1987 but may have been expanded or renovated since that time, to accommodate the growing prison population. Prisoners are housed in separate areas depending on the crimes they committed, their current risk assessment, and their behavior. This facility is currently under the supervision of Chief Joe A. Lizarraga and houses male and female offenders.

If you have a family or loved one that is currently incarcerated at Mule Creek State Prison, the first thing you should do is contact the prison for information on the inmate. Based on the information you are provided, you would then contact either a criminal defense lawyer or a bail bond service. They will provide you with vital information which can be used to defend an individual and in a lot of cases get them released from detention while awaiting trial.
