The county officials of Bexar County said on Tuesday that they are investigating the possible link between the death of Sergeant Kenneth Vann, their sheriff’s sergeant, and Mexican drug cartel. Vann was ambushed while he was sitting in his patrol car.

County Sheriff Amadeo Ortiz said that Vann may have been targeted because he was in the government’s side.

Vann was in his uniform and was sitting in a marked patrol car Saturday when a white car parked beside him. Then, somebody from the car aimed and shot at Vann; that person fired an average of 28 shots from an automatic weapon. To date, no suspects are still in custody.

Ortiz said that they see no evidence that Vann was followed that morning, indicating that he was not targeted personally. Ortiz added that Mexican drug cartels may have picked him because he was a symbol of authority. He said that it could have just been an attack on a random law enforcement officer.

Ortiz stressed that he sees no reason for the general public to feel alarmed. He further said that the FBI and the Texas Department of Public Safety, along with other law enforcement agencies, are all working hand-in-hand in working with the investigation.

Deputy Lou Antou said they are reviewing surveillance videos from the gas stations in the corner where the incident took place. Vann was parking in a corner on the southeast side of San Antonio when he was killed.
