Valley Park, Mo. ? A transient was accused Saturday of abducting, trying to rape and ultimately slaying a 6-year-old girl whom he allegedly snatched from her father’s home.

St. Louis County warrants charge Johnny A. Johnson, 24, with first-degree murder, armed criminal action, kidnapping and attempted forcible rape in Friday’s killing of Cassandra “Casey” Williamson, who vanished from the home where Johnson had spent the night as a guest.

Cassandra’s body was found blocks away at an abandoned glass factory where police say Johnson sometimes slept. Johnson told police the girl’s location, investigators said.

Johnson was held without bond Saturday in the St. Louis County Jail in Clayton. It was not clear when he would make his first court appearance.
