But two law enforcement officials familiar with the investigation said the teenager, arrested Sunday in Duluth, Minn., is suspected of helping Jeff Weise, 16, plan last week's assault and had expected to be part of the rampage. Prosecutors are considering whether to charge the juvenile as an adult with conspiracy to commit murder, the officials said.
Authorities have not ruled out more arrests and are continuing to question other teenagers about whether they knew about Weise's plans beforehand, the law enforcement officials said.
The arrest represents a surprising shift in the investigation of the March 21 killings, and was announced on the same day that Weise and three of his victims were laid to rest in funerals. Weise killed nine people, including five students and a teacher, before killing himself. He has been portrayed as a troubled loner with a history of depression, family tragedy and violent fantasies.
