HOUSTON — The gunman who shot and killed an undercover police officer during a Tuesday night sting operation was an illegal immigrant who had been picked up by the U.S. Border Patrol in El Paso and allowed to return home to Mexico 10 years ago.
Municipal records also show that Roberto Pedroza Carrillo, 37, had been stopped and ticketed by the Houston Police Department at least four times since 2002, most recently last November. In 2002, a warrant was issued for Carrillo after he failed to appear in court on a speeding ticket, but the case was resolved when he paid the fine.
