As a memorial service was held in his home state of Colorado for an American said to have been shot and killed by Mexican pirates on a lake on the Mexico-Texas border, Mexico’s president was responding to criticism of his government’s reaction to the slaying.
At the service on Sunday, a Texas lawmaker said the death will be remembered as he fights to secure the border. Texas state Rep. Dan Flynn’s letter to Tiffany Hartley was read during a memorial service for her husband, David Hartley, 30.
His body has never been found. The search by Mexican authorities was suspended after the lead investigator was beheaded in an apparent warning by cartel enforcers.
Hartley’s family criticized the Mexican government in the days after the shooting, claiming they weren’t doing enough to find his killers, or his body, points out CBS News Correspondent Don Teague.
