Benjamin Ross, 39, of San Antonio was killed on May 3, 2014. His body and vehicle were found burned in the 21000 block of Highway 281 South. Investigators determined Ross had been shot before the burning.

The Bexar County Sheriff’s Office arrested 40-year-old Omar Hartfield and says Hartfield confessed in an interview, alleging an argument over theft of drugs led to the shooting. Authorities also say Hartfield did not act alone and that others may have assisted, though no additional arrests have been announced. Hartfield is being held on unrelated parole violations.

Ross had a prior contact with law enforcement: an arson charge involving a vehicle about 24 years earlier. The investigation remains open as detectives continue to pursue leads and evidence.

Did anyone in the San Antonio area have information about Ross, his movements around May 3, 2014, or others who might have been involved?
