A New Mexico prosecutor's spokesman says an 18-year-old man accused of killing a nun on the Navajo reservation pleaded not guilty Thursday to first-degree murder and burglary charges.
U.S. Attorney spokesman Norm Cairns says Reehahlio Carroll of Navajo appeared in federal court in Albuquerque.
Carroll entered pleas to the murder and burglary charges, but Cairns says the judge entered a not guilty plea for Carroll on a charge of transporting a stolen vehicle in interstate commerce.
His defense attorney did not return a message seeking comment.
Carroll is accused of killing 64-year-old Sister Marguerite Bartz while burglarizing her home in Navajo. She was found dead Nov. 1.
Authorities say Carroll took a mini-SUV used by Bartz. It was recovered in Arizona.
