 On September 18, 1975, Yoshimura was arrested with Hearst in a second-floor apartment at 625 Morse Street by FBI Special Agent Tom Padden and San Francisco Police Department Inspector Tim Casey.Padden and Casey, failing to read Hearst and Yoshimura their Miranda rights, did not obtain a warrant until twenty-six hours later; thus weapons evidence including a handgun in Yoshimura's purse and a shotgun in the bedroom was suppressed.During her trial, Japanese Americans who empathized with her family's experience during World War II gave $150,000 to aid her legal defense conducted by the Asian Law Caucus, and led by Garrick Lew , through the Wendy Yoshimura Fair Trial Committee.
