According to court papers, the 13-year-old boy told other students, "I'm going to kill you" and "you are on my kill list."
His family claims the boy has never been in trouble with the law, has not been bullied and is not a threat to anyone. Members of the family filled the juvenile courthouse on Monday and attempted to convince a judge that they'll keep an eye on the boy around the clock if he's allowed to come home.
Prosecutors say they teenager's alleged hand-written kill list made fellow students fear for their lives.
"This was an extremely disruptive event in the school environment and people were afraid of the threats the respondent made," the prosecutor said.
Some parents in the small town of Eatonville doubt the boy was actually planning to hurt anyone, but they agree he shouldn't be near school and that it might be best if he remains locked up.
"I don't want to say that he meant it or that he was going to carry it through, but you can't take that chance that he's not, because it does happen," said Jessica Graham, whose brother attends the same middle school.
According to court documents, a fellow student turned the boy in after discovering that he made a kill list every day, as well as a no-kill list. The principal allegedly found one kill list naming five students in a recycle bin at school last Friday.
Despite those lists, Eatonville school superintendent Rich Stewart insists there is no danger at the school.
"The kids are safe. We want parents to know everything's going well at the middle school," Stewart said.
While investigators try to determine why the boy allegedly made the kill lists, the tight Eatonville community is waiting for answers.
"It's absolutely heart-breaking, but this is reality. This happens these days," Graham said.
A judge ruled that the teenager should remain in custody until investigators have more time to evaluate him. They'll take up the question of release on Thursday.
In the meantime, the boy has been expelled from school.
