Police in St. Louis County have found the body of a young girl – a body believed to be that of 6-year-old Cassandra “Casey” Williamson, who disappeared from a Valley Park home around 7:20 Friday morning. The disappearance of the 6-year-old led to police questioning of a transient identified as 24-year-old Johnny Johnson. He was known to the Williamson family and had spent the previous night in the same home in which Casey Williamson had slept. Police say the questioning resulted in information that led them to the girl’s body. The body was found at an abandoned glass factory a short distance from Casey Williamson’s home. Johnson, they say, is the only suspect in the case.
