The Nebraska Court of Appeals has affirmed the attempted kidnapping conviction of man who forced a teenage boy into his car.

Jose Llerenas-Alvarado pleaded no contest to the charge last year and was sentenced to 10-to-15 years. Llerenas-Alvarado tried to withdraw his plea before his sentencing, saying he hadn’t been advised that his conviction could lead to his deportation.

On Tuesday, the Nebraska Court of Appeals affirmed his conviction, saying Llerenas-Alvarado had been told twice at previous hearings that he could be deported if found guilty of the crime.

Authorities say Llerenas-Alvarado propositioned the boy last summer in Newman Grove. When the boy refused, Llerenas-Alvarado forced the teen into his car, drove out of town and attempted to assault the boy. The teen broke one of his arms while escaping.
