Six Colombians accused of in the death of a DEA agent last month have been indicted by a federal grand jury for kidnapping and murder, the Associated Press reports.

DEA Agent Terry Watson was working in Colombia when he was allegedly attacked in a taxi cab in what officials say was a robbery attempt.

Watson, who was on temporary duty in Bogota, was stabbed to death and shot with a stun gun.

According to investigators, the six Colombians operated an abduction and robbery ring by luring people into taxi cabs.
