"His face looked like he had taken several blows to the face," said principal Greg Schwab. "I've never seen anything like this. This is just, this is a first time for me... and it's very disturbing to me on a personal level because I know the student."
The 18-year-old suspect, Darian Sharpe, went before a judge Wednesday.
Investigators say Sharpe followed the 16-year-old into the bathroom, then punched the boy before stealing his wallet. The victim lost a tooth and broke his jaw in several places during the attack.
"The victim ended up with relatively severe injuries in this case," the prosecutor told the judge in Snohomish County Superior Court Wednesday. "Which is why I'm asking for a high bail."
Sharpe tells a different story, claiming the victim came at him with a knife.
"He says he was attacked," said Amanda Sharpe, Darian's mother. "So we need to get to the bottom of it because sometimes the situation isn't as it first appears."
Amanda Sharpe says her son is a good kid, headed for the Marines.
She didn't know about some of his prior arrests for assault, hit and run, and harassment.
"No, I wasn't aware of the harassment," she said.
Schwab says Sharpe has been expelled and parents have been notified. He insists his campus is safe, and is working to see if students knew in advance of the attack and could have spoken up.
"This incident proves for us that there's things we need to work on, obviously," Schwab said.
Police says there's no clear connection the boy was targeted because he's in the special education program. They say it could just be a random robbery, or a case of bullying gone too far.
