Sister Marguerite Bartz, 64, was found in a pool of blood late one evening in 2009 after she didn’t show up for Mass on the Navajo Indian Reservation.
But now, Reehahlio Carroll has confessed to breaking into the nun’s trailer home.
He said he was looking for money and items that could be traded for cash or drugs and alcohol.
Carroll said he beat her over the head with a flashlight and then strangled her to quiet her moans pleaded guilty.
U.S. Attorney Ken Gonzales has noted the "tragic irony" of Bartz falling victim to the high rate of violence on the reservation, saying she "was a woman who dedicated her life to bringing peace and harmony to the Navajo Nation."
