FARMINGTON — A Shiprock man is facing life in prison after pleading guilty Tuesday to a federal arson charge, Acting U.S. Attorney Steven Yarbrough announced Tuesday.

Dan Curtis Thompson, 32, and his twin sister, Christina Thompson, were arrested in October in connection to a January 2013 fire, according to the U.S. Attorney's Office for the District of New Mexico.

Dan Curtis Thompson on Tuesday admitted in court that he set fire to his former girlfriend's home, which was a Navajo Housing Authority rental unit in Ojo Amarillo.

He said his sister drove him to the home, and then he shattered a window to unlock the door, poured gasoline inside the unit and ignited it.

He said in court that he didn't check to see if anyone was home when he set the unit on fire, and he caused the fire to retaliate against his ex-girlfriend, according to the U.S. Attorney's Office.

Dan Curtis Thompson has been in custody since his arrest and will remain in custody until his sentencing hearing.

Christina Thompson has pleaded not guilty to charges. She is set to go to trial on April 14. She is currently on conditions of release pending the April trial.

The case is being prosecuted as part of a federal initiative to counter violence against native women, according to the U.S. Attorney's Office.
