Officer Prock was first to be killed in line of duty at DVI
By Lt. Arnel Bona, AA/Public Information Officer
Deuel Vocational Institution
On June 26, 1963, a young Deuel Vocational Institution correctional officer lost his life at the hands of two inmates.
Officer Connie “Conn” Prock thought he was rushing to break up a fight but found himself ambushed by two inmates wielding inmate-manufactured weapons. He was stabbed to death. Officer Prock was fairly new on the job, starting at the institution only a year prior. He was the first officer to be murdered in the line of duty at DVI.
(Editor’s note: Another Officer, Raymond Messer, was murdered in 1951 when it was in Lancaster and known as California Vocational Institution.)
In a June 22, 1963, edition of the Lodi News-Sentinel, DVI Superintendent Allen Cook said Prock was “a very well-liked young man … by both employees and inmates.”
To mark the 52nd anniversary of the slaying, DVI acting Chief Deputy Warden John Garza, Correctional Officer Derrick Casey (California Correctional Peace Officers Association chapter president) and members of the DVI Honor Guard laid a wreath at Officer Prock’s grave.
The wreath was donated by the DVI CCPOA.
