Claiming he was a danger to himself and other students, Tudesko was suspended and eventually handed a year-long expulsion.
His mother, Susan Parisio, said, "What happened to him wasn't right," Tudesko's mother Susan Parisio said.
Parisio said it's an important distinction that her son's truck was parked on a public street. "I asked the police and the district attorney's office if he did anything wrong and they said no," Parisio said.
However, school officials disagreed. They told Parisio state law gives them "the right to search any of the student's vehicles no matter where they're parked or what they're doing during school hours," she said.
The NRA came to Tudesko's aid, saying school officials are misinterpreting the law. An NRA lawyer plans to be by Tudesko's side when he appeals his expulsion Tuesday at the Glenn County Office of Education at 10 a.m.
Tudesko said he's eager to return to Willows High and graduate on time with his class.
