KING COUNTY, Wash. -- Parents of children in the Tahoma School District are outraged they were not told about a so-called "hit list" with their kids' names on it for months after it surfaced. The list, written by a troubled teenager, outlined how he would kill his classmates.

The list came to light after an incident on April 3 at Tahoma Junior High School in Maple Valley.

According to a report by the King County Sheriff's Office, a 13-year-old student claimed he had poisons including Abrin, Strychnine and Iodine in his backpack and was intending to commit suicide using the substances. He told investigators that he had bought Abrin seeds off the Internet.

The seeds, if processed correctly can produce a deadly poison if ingested. But because the student had not processed the seeds to create the poison, the state crime lab determined that the seeds were not a threat.

"The student was expelled for causing a significant disruption to school," said Kevin Patterson, spokesman for the Tahoma School District.

But when detectives searched the student's Maple Valley home, they found two copies of what's being described as a hit list, both in a handwritten rough-draft form and a typed final-draft form.

The list contained the names of seven students from the school, along with details on how the students would die. The report stated the "CODs," or causes of death, included shootings, stabbings, electrocutions and bombings as well as the use of Abrin in some cases.

Sheriff's spokesman John Urquhart said detectives determined that the threats were "fantasy" from a troubled child with problems.

"He has a history of emotional issues and was not really a threat, most likely, either to the school or persons on the list or anybody else in the school," he said.

Nevertheless, the sheriff's office and the school district chose not the contact the parents of the seven students on the list that when it was found.

Carrie Ravencroft, whose daughter was on the list, was first contacted by a sheriff's detective near the end of August, nearly four months after detectives had discovered the list.

"It's absolutely absurd that they feel that wasn't a threat," said Ravencroft.

The school district had sent out an e-mail to Tahoma Junior School parents of the poison scare immediately after the incident, but had chosen not to notify anyone about the existence of the list.

"Once the police were involved, we felt it was their investigation and we should not interfere with a police investigation" said Patterson.

According to the sheriff's report, detectives first learned on May 21 the school had not alerted parents about the found list.

Still, it wasn't until late July that detectives in consultation with legal advisers decided it was time to notify the parents and the students on list as a part of "due diligence." By then detectives had already determined the threats were not credible.

Urquhart said the school is free to notify parents of these types of situation.

"Typically we leave that up to the school until we are more into our investigation," he said.

But Ravencroft doesn't buy the explanations.

"Parents should be told of any threat against their kids. It's the school's number one responsibility and that's safety," she said.

The student was expelled in April, but was reinstated back into school at the end of July after personally meeting with district superintendent Mike Maryanski, Patterson said. Detectives were not made aware of the reinstatement until a month later, according to the sheriff's report.

When Ravencroft and her mother Sandi found out about the reinstatement, they obtained a restraining order last Friday preventing any contact between their daughter and granddaughter with the student.

The student attended the first day of classes on Tuesday but had not been served the restraining order. That night, parents of kids on the list met with the school board to air their concerns.

On Wednesday morning, Maryanski and Rob Morrow, the principal of Tahoma Junior High School, decided to expel the student permanently.

"He was expelled for being a disruptive influence in school environment" said Patterson.

The parents plan to press the school board and the King County Sheriff's Office for more answer as to why they weren't told about the hit list sooner.
