Timothy M. Brennan and Robert Ladd Timothy M. Brennan (aka "Blondie") (born March 2, 1959) and Robert Ladd (born February 19, 1959) joined the Compton Police Department as officers in 1982 and 1983, respectively.

The police department could only afford to have two people at the time, even though many smaller cities typically had up to four times as many. As the gang unit, Brennan and Ladd were responsible for dealing with and investigating over fifty-five gangs in the 10.1 square mile area that make up the City of Compton. They have served as the primary or assisting investigating officers on hundreds of gang-related murders and thousands of gang-related shootings, and witnessed instances of gang-related rapes, robberies, drive-by shootings, and shootings at police officers.
