A federal grand jury has charged a teenager accused of killing a nun at her home on the Navajo reservation with first-degree murder.
The U.S. attorney's office in Albuquerque said Thursday that 18-year-old Reehahlio Carroll also is charged with burglary and transporting a stolen vehicle in interstate commerce.
Carroll is accused of killing 64-year-old Sister Marguerite Bartz while burglarizing her home in Navajo, N.M. Bartz was found dead Nov. 1.
Carroll also is accused of taking a vehicle Bartz used. Authorities found the mini-SUV in Arizona.
The U.S. attorney's office says the alleged murder was a first-degree felony because it took place during a burglary.
Prosecutors say if Carroll is convicted of all the crimes, he faces an automatic sentence of life in prison without parole.
