In early April 1978, the Yu brothers (Tom, Chester, and Dana) hired an attorney, George Walker, to make a plea bargain; in turn, their attorney met with the assigned assistant district attorney, Hugh Levine, on April 3 and explained his three unnamed clients were requesting immunity for two brothers (Tom and Dana Yu) in exchange for their testimony against the shooters. Walker described those two brothers as peripherally involved, specifically calling Tom Yu "a peripheral figure who had inadvertently answered a telephone call at the house in Pacifica" which had informed him that members of the Wah Ching and Hop Sing were at the Golden Dragon. The third brother, Chester, admitted to his role as the getaway driver, but requested for his proceedings to be held in juvenile court in exchange for his testimony. Levine tentatively agreed to allow the driver to enter juvenile court and provided immunity to the two brothers, conditioned upon confirmation that (1) they were only peripherally involved in the crime and (2) their testimony was truthful. Levine met Walker's three clients for the first time on April 19; Dana Yu's request for immunity was granted, and Chester Yu was allowed to enter the juvenile court system. However, since Levine already knew that Tom Yu, as a leader in the Joe Boys, could not have been involved only peripherally, immunity for Tom Yu was rejected.
