FARMINGTON — A Shiprock man who police say killed a women and two of her adult children last year while drunken driving on the Navajo Nation was charged Friday in federal court with three counts of second-degree murder, according to a U.S. Department of Justice news release.

Tillman Naskia Begaye faces three possible life sentences, said Elizabeth Martinez, a spokeswoman for the U.S. Attorney's Office for the District of New Mexico.

On July 14, 2013, the 33-year-old man drove his full-sized pick-up truck into the oncoming lane on U.S. Highway 491 south of Newcomb, and he crashed head-on into the vehicle the woman and her two children were in, according to the news release.

The three died at the scene, according to the release.

Begaye's blood-alcohol content was .18, more than twice the legal limit, when drawn an hour after the crash at a nearby hospital, according to the release.

Begaye has two previous drunken driving convictions, according to the news release.
