(Douglas) Thomas was sentenced to death for the November 1990 capital murders of Kathy and J.B. Wiseman. Thomas was 17 years old at the time of the crime. Thomas had been dating 14 year old Jessica Wiseman, the daughter of Kathy and "J.B." for a while before the murders. Their relationship was serious and her parents did not approve. They pressured Jessica to break-up the relationship with Thomas, however, Jessica was unwilling to do so. She became angry with her parents and stated that she wished they were removed from her life. In his confession Thomas stated that he had smoked some marijuana on his way over to the Wiseman house and carried with him a shotgun. He said Jessica helped him in the window and they then arranged some drugs on the floor to make it appear to be an attempted robbery. Thomas then went down the hall to the Wiseman's bedroom and shot them as they slept. Thomas said Mrs. Wiseman did not die from the first shooting and Jessica implored Thomas to shoot her again. He did, killing her instantly. Jessica was tried as a juvenile and was released when she turned 21.I read where he was executed for it. I'll have to do some searching on that case.
