In 1987, 30-year-old John Robert King phoned the El Paso police, claiming that on May 24, 1986, he, together with 33-year-old Gerald Peter Zwarst, attacked Shelley Sikes while she was in her car, after which the girl was raped and strangled. After his arrest, Zwarst told the police that he had hidden the body in one of the fields, where the other bodies were found. Both men were asked to indicate the whereabouts of Sikes' body in exchange for dodging the life sentence, but their directions failed to uncover it.
