A fatal crash on Highway 99 on May 19, 2017 ending the life of John Russom, 56, of Oroville has resulted in a 10 year state prison sentence for 71-year-old Frank Mattos of Gridley.

Mattos was sentenced Thursday after previously pleading no contest to a felony count of gross vehicular manslaughter while intoxicated. Judge Michael Deems sentenced Mattos in Butte County Superior Court.

Witnesses reported that the vehicles collided head on when Mattos turned in front of the victim's southbound vehicle which had the right-of-way. Mattos had slowed to make a left turn toward a driveway near Dakota Avenue traveling north.
