Randall’s current assignment is the Facility Manager of the Main Adult Detention Facility where he is responsible for managing the daily operations of an 845-bed medium/maximum security facility.
The Main Adult Detention Facility (MADF) is located at 2777 Ventura Avenue in the Hall of Justice Complex.
The Main Adult Detention Facility (MADF) was opened in 1991. This "new generation" facility was based on a "direct supervision" design, as opposed to the "linear" design of the County's earlier jails. Originally designed to hold close to 500 inmates, the facility quickly reached its housing capacity and an expansion was opened in 1997 to provide an additional 290 beds. The facility is a medium/maximum security facility, housing both pre-trial and sentenced inmates.
The direct supervision concept at MADF encourages officer contact with inmates and emphasizes the use of interpersonal communication skills. Officers provide a leadership role and make themselves available to inmates by using the new generation/direct supervision model for inmate management.
Currently, facility staffing includes 145 Correctional Officers, 18 sergeants, 5 lieutenants, and one captain. Support staff includes 29 legal processors, 22 detention assistants, 18 cooks and 7 janitors.
