Biography
C. J. Sullivan was from Los Angeles. C. J. Sullivan received a five-year prison sentence, which he served in Folsom from July 12, 1923, until his term expired.
The International Labor Defense holiday roster in the December 29, 1925 Daily Worker lists this prisoner, printed as C. J. Sullivan, at Folsom California. This documents confinement at the roster’s reporting time, without establishing an admission, transfer, release, new conviction or complete duration. Existing independently sourced custody chronology remains separate. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1925/1925-ny/v02b-n297-NYE-dec-29-1925-DW-LOC.pdf#page=5
The May 1927 Labor Defender explicitly lists C. J. Sullivan among prisoners actually released, giving February 12, 1927. This contemporary completed-release report corrects the earlier missing or conflicting endpoint. It does not establish complete continuous custody or turn an imposed term into actual time served.

The December 17, 1924 Daily Worker political-prisoner subscription roster individually lists C. J. Sullivan under Folsom Prison, Represa, California. This supplies the institution already described in the biography, without identifying a new admission, release or period actually served.
