Parker County Sheriff Russ Authier is expected Thursday to discuss the investigation into a triple homicide that happened late last month. On April 24, the bodies of 44-year-old Tiffany Ann Williams, 42-year-old David Wayne Walker and 55-year-old Robbie Allen Head were found near a water-filled creek in northern Hood County.

The Parker County Sheriff's Office released new details Thursday about a triple murder in the county last week. Sheriff Russ Authier believes the motive was drugs and money, and the suspects and victims knew each other.
