Jerry Frank Townsend is mentally retarded, with the mental capacity of an eight year old. Nevertheless, he was convicted of six murders and one rape and sentenced to seven concurrent life sentences. In 1979, Townsend was arrested for raping a pregnant woman in Miami, Florida. During the investigation, he confessed to other murders. The confessions were largely the consequence of Townsend wanting to please authority figures, a common adaptive practice by someone with his mental capacities. Police took Townsend to murder scenes and recorded his confessions. In 1980, Townsend was convicted of first-degree murder for the 1973 killings of Naomi Gamble and Barbara Brown in Broward County. Not only did Townsend confess to these two murders, but he also confessed to the murder of 13 year old Sonja Marion in 1979. In 1982, he pled guilty to two slayings in Miami in the late 1970s and no contest to two 1979 murders in Broward County.
Eventually, Townsend was cleared by DNA evidence following actions in 1998, when Sonja Marion's mother had a Fort Lauderdale police detective review the Townsend cases.
