Truman Harrison, a 66-year-old man from Sheffield, Texas, was found shot to death inside his home on the morning of Thursday, September 25, 2025. Deputies with the Pecos County Sheriff's Office responded to a residence on Main Street after a report of a man down; investigators quickly treated the case as a homicide. The Texas Rangers joined the scene and assisted with forensic processing and early interviews as authorities worked to reconstruct Harrison's final hours.
By the following day, Friday, September 26, investigators announced the arrest of Arlie Sparkman of Sheffield on a murder charge in connection with Harrison's killing. Officials said Sparkman was taken into custody without incident and booked into the Pecos County Jail, with Sheriff Thomas Perkins publicly crediting the Texas Rangers and their forensic team for their role in the swift arrest. Local coverage placed the scene of the killing along the 200 block of Main Street and identified Harrison as the victim discovered inside the home.
Subsequent reporting referenced an arrest affidavit that outlined early evidence gathered by investigators, including doorbell-camera videos that purportedly showed Harrison and Sparkman together on the night of September 24, the evening before Harrison was found dead. Authorities have not publicly released a motive, and no additional suspects were announced by law enforcement at that time. The case remained in the hands of Pecos County authorities with assistance from the Texas Department of Public Safety and the Texas Rangers as the legal process moved forward.
