RENO, Nev. (AP) – Prosecutors in Nevada have filed three new rape charges against a former Marine accused of killing a college student.

James Michael Biela was charged Friday with the rapes of Briana Denison and another woman. He was also charged with attempted sexual assault of a student in November 2007.

The 27-year-old was arrested Nov. 25 and charged with strangling Denison and sexually assaulting another woman in December 2007.

Washoe County prosecutors were reviewing whether to seek the death penalty.

Denison, a Santa Barbara City College sophomore, was abducted from a friend’s house, and her body was found in a Reno field.

Denison’s family declined to comment. Calls to the county public defender’s office were not answered Saturday.
