TAMPA - Bob Anderson Mitcham, a longtime and colorful Hillsborough circuit judge, died Wednesday. He was 76. Known as "Preacher Bob," Mitcham presided over many high-profile trials, including the case of three young friends accused of pulling up a stop sign as a prank that caused the traffic deaths of three teenagers. Mitcham reluctantly retired in 2001 because of health problems. In his retirement, he wrote a book called Justice From Buttermilk Bottom, detailing his rise from the hardscrabble streets of southside Atlanta through his legal career. A memorial for Mitcham is scheduled for Saturday, May 8, at 11 a.m. at Stetson University College of Law in Tampa.
