Lake Charles –


Earlier this morning at approximately 1:00 a.m. the Calcasieu Parish Sheriff’s Office responded to a call near the intersection of Etienne Daigle Road and Raleigh Reed Road in Sulphur in reference to a man being hit by a truck. 


The initial investigation revealed Mark E. Brock, 61, Sulphur, the driver of a pickup truck, was traveling northbound on Etienne Daigle Road when he struck a pedestrian who was walking in the middle of the northbound lane on Etienne Daigle Road.  The pedestrian, Jonathan P. Hatfield, 42, Lake Charles, was transported to a local hospital and later pronounced dead. 


When deputies spoke with Brock they detected a strong odor of alcoholic beverages emitting from his breath and he confirmed to deputies he had been drinking.  After Brock performed poorly on standard field sobriety testing a warrant was obtained for a blood draw for toxicology testing.


Brock was arrested and booked into the Calcasieu Correctional Center and charged with DWI 1st; and vehicular homicide. 


Several factors are believed to have contributed to the fatality including the area being dark with no street lights. 


CPSO Sgt. Terry Faulk is the lead investigator on this case.



Note: In order for the mugshot to be released for the charge of vehicular homicide the suspect’s BAC must be greater than .20%.  Brock’s BAC is pending toxicology testing.
