A jury in Ocala, Fla., recommended that a man convicted of arranging for his mother to be killed be sentenced to life in prison for the deaths of four other people slain by mistake. Dorsey A. Sanders III, 33, was convicted on four counts of murder, conspiracy and accessory in the Floral City slayings. He could receive the death penalty when Circuit Judge John Thurman sentences him on Aug. 19. Prosecutors said Sanders, 33, hired John C. Barrett, 26, to kill his mother, JoAnn Sanders, to prevent her from receiving $500,000 in a divorce settlement from his father. They said Barrett botched the job and instead killed four men working at Mrs. Sanders' home.
