A former usher for University of Southern California football games has been sentenced to 16 years to life in prison for fatally stabbing a USC film student from Idaho. Deputy District Attorney Kennes Ma says 25-year-old Travion Ford was sentenced Thursday after a jury convicted him in August of second-degree murder for killing Bryan Frost, 23, of Eagle, Idaho, on Sept. 18, 2008. The altercation started when Frost and two other students passed Ford on a street near campus in the early morning hours, noisily slamming a metal gate. After Ford yelled at the group, he ran back into his mother's house and grabbed a kitchen knife. Prosecutors said he stabbed Frost in the heart.
