In March 1983, 19-year-old Christina (Christine) Castiglione was reported missing from Redford Township on March 21. Eight days later her partially clothed body was found in a remote, wooded section of the Oak Grove State Game Area in Deerfield Township. An autopsy determined she had been sexually assaulted and strangled to death.

Male DNA was collected at the scene and entered into CODIS in the early 2000s with no match. In March 2022 preserved evidence was sent for advanced genealogical testing; that testing pointed investigators to Charles David Shaw. Shaw had died in November 1983 and therefore was never charged. Investigators found no documented direct connection between Shaw and Castiglione, though he had lived within about five miles of where she disappeared and had a prior arrest for an attempted abduction in 1981.

If anyone knew Christina, lived near Oak Grove State Game Area in 1983, or has information about Shaw’s activities that spring, please come forward.
