A 41-year-old man was set to be released from prison this week after his defense said DNA evidence showed he was wrongly convicted of murder and rape 26 years ago and a judge ordered him freed. The man, Anthony Caravella, was found guilty in the 1983 attack and sentenced to life in prison. Mr. Caravella, who is mentally disabled, was 15 at the time. Prosecutors had sought the death penalty for Mr. Caravella, who was accused of raping, strangling and stabbing Ada Cox Jankowski, 58. She was found dead near an elementary school in Miramar, in South Florida. Mr. Caravella confessed to the crime, but his lawyer said the police beat him to coerce the admission.
