FARMINGTON — A 21-year-old Kirtland man was convicted Wednesday in federal court on two counts of sexual abuse after a three-day trial in Santa Fe.

Steven Michael John, an enrolled member of the Navajo Nation, was indicted in August 2013 on one count of attempted aggravated sexual abuse and abusive sexual contact.

The indictment alleged John broke into a residence in Sanostee on July 18, 2013, and attempted to rape a 16-year-old Navajo girl, according to a press release from the U.S. Department of Justice.

The girl, who was taking a shower at the time, managed to defend herself and called 911. The 911 call, photographs of the injuries sustained during the assault and professional medical testimony were presented as evidence during the trial, the release states.

John could face a maximum sentence of life in prison. His sentencing hearing has not yet been scheduled.

The case was investigated by the Farmington office of the FBI and the Shiprock office of the Navajo Police Department. Assistant U.S. Attorney Jennifer Rozzoni prosecuted the case, with assistance from Kristopher Houghton, a contractor with the U.S. Attorney's Office.
