GERING, Neb. (AP) – A Colorado resident has been imprisoned for sexually assaulting one of his art students in western Nebraska. Scotts Bluff County District Court records say 45-year-old Steven Barraza, of Englewood, Colorado, was sentenced Thursday to 10 to 20 years in prison. The court records say a woman told authorities she and Barraza had sex twice in 2014, when she was 15.
