DSP Sergeant Keesee was on-duty and driving southbound on U.S. Highway 84 near the town of Goldthwaite when the fatal crash occurred. His patrol vehicle left the roadway. It then went over a guardrail and landed in a creek bed.
No communication about the accident was received from the sergeant indicating he may have been killed immediately or at least been left unconscious until he later died from injuries in the accident.
A passing motorist later noticed debris on the roadway and reported the accident. The DPS is investigating the accident to attempt to determine the time of the crash and its cause.
