On April 20, 2025, Tiffany Ann Williams, 44, was among three people murdered in northern Hood County, Texas. Tiffany, her husband David Dewayne Walker, 42, and Robbie Allen Head, 55, were reported missing April 21 after a family member found the Granbury home in disarray, the Ring doorbell missing, and the victims unreachable. Their bodies were found April 24 near a creek along FM 167; all three had gunshot wounds and investigators determined the killings occurred April 20.

Arrest affidavits allege that 27-year-old Trin Lawrence McKnight and 19-year-old Barrett Copeland planned a robbery of the home because they believed drugs and money were inside. During the robbery, all three victims were shot, then wrapped, loaded into the victims’ vehicle and left near the creek. A bloody fingerprint on the victims’ car is cited in the probable-cause paperwork. An 18-year-old, Michael Morris, was later charged with tampering with evidence, abuse of a corpse and failure to report a felony for allegedly helping clean the scene and dispose of the bodies.

A fourth man, Dennis Craig Alexander, was initially arrested but later released after investigators concluded he had been falsely implicated by McKnight and Copeland. The investigation into this triple homicide is ongoing. If anyone has information about Tiffany, her husband, Robbie Head, or the events around April 20 in Granbury, please come forward.
