A helicopter carrying a Border Patrol agent and three National Guard members crashed along the U.S.-Mexico border in South Texas on Friday afternoon, killing three and badly injuring a fourth person.
Two victims were identified Sunday as members of the New York State National Guard. John Grassia III, 30, was a chief warrant officer and New York State trooper, and Casey Frankoski, 28, was a National Guard chief warrant officer. U.S. Border Patrol agent Chris Luna also died, federal officials confirmed.
