Gregory Treace, 52, vanished from the Sapulpa, Oklahoma area in late July 2022. On the evening of July 23 he left his Tulsa home for a planned fishing trip with his brother and the brother’s girlfriend; their vehicle broke down in Jenks and the next morning they were given a ride to their mother’s rural property west of Sapulpa. The brother says Gregory was last seen walking on a trail on that property on July 24. Gregory was undergoing treatment for stage 4 non-Hodgkin’s lymphoma at the time.

Search teams used K9 units and drones to sweep roughly 30 to 40 acres of the mother’s land but turned up no trace. A few personal items — Nike shoes and jean shorts — were found on a bench near the house, while his wallet, phone, keys and a prescription bottle were missing. Accounts of what happened that night conflict; the brother’s story reportedly changed and a witness said the brother was seen yelling at Gregory. The brother has since been jailed on unrelated charges and investigators have interviewed family members, but no charges relate to Gregory’s disappearance.

What information might help clarify Gregory’s last movements on the mother’s property?
