David Dewayne Walker, 42, and his wife Tiffany Ann Williams, 44, were reported missing from their Myrtle Lane home in Granbury, Texas, on April 21, 2025, after a family member found the house in disarray, the Ring doorbell removed, and the couple’s vehicles still parked outside. Investigators found large amounts of blood and spent shell casings inside the residence and determined the murders occurred on April 20 at the couple’s home.

On April 24 their bodies were recovered near a creek along FM 167 in northern Hood County along with the body of 55-year-old Robbie Allen Head. All three victims had sustained gunshot wounds. Authorities arrested 19-year-old Barrett Copeland and 27-year-old Trin Lawrence McKnight in connection with the killings; a third man, 45-year-old Dennis Craig Alexander, was initially arrested and later released. McKnight’s bloody fingerprint was found on the driver’s door of the victims’ vehicle. McKnight told investigators that the three had planned to rob the victims, alleging Alexander held them at gunpoint while others searched the house and that Alexander shot all three victims before their bodies were disposed of.

Did anyone in the area see activity on Myrtle Lane or along FM 167 around April 20–24 that could help investigators?
