The FBI has confirmed Ramon Arellano Felix, the enforcer of the most notorious drug cartel in Mexico, was killed in a gun battle with Mexican police Feb. 10.
Jan Caldwell, FBI spokeswoman in San Diego, said DNA tests done in the FBI lab in Washington, D.C., confirmed the death of Ramon Arellano. He was shot by police in Mazatlan, where authorities have said Arellano traveled to kill a rival drug cartel member.
The confirmation of his death comes as another Arellano brother, Benjamin Arellano Felix, has been held over to stand trial on drug charges. Benjamin Arellano was considered the "brains" of the operation, handling the day-to-day business of the cartel. He was arrested March 9.
The brothers were considered to be the heads of the cartel. However, there are others in the family who could take over the operation.
