Brianna Denison, a 19 year old student, disappeared on January 20, 2008. Her body was found 26 days later in a field in south Reno. She had been strangled and raped. James Biela is currently on trial for her death and the sexual assault of two other college students in late 2007. Biela was identified as a result of a familial DNA match when DNA was provided from his four year old son. Prosecutors said they expect their case will take until the end of this week. Biela could face the death penalty if convicted.
