The Gilham Family Murders - 703

Oct 5, 2026 · 44m

Summary

This episode investigates the 1993 Woolanarra murders where Jeffrey Gillam was convicted of killing his parents and brother, a case fueled by his uncle’s suspicion and inheritance disputes. The hosts analyze conflicting evidence, including carbon monoxide levels and a potential bloody fingerprint on an intercom, that suggest Christopher may have killed his parents before Jeffrey retaliated. After a retrial and a divided appellate court decision, Jeffrey was acquitted in 2012, leaving the true killer unknown and the case unresolved.
