The teens tried to talk their way out of it.

"They kept saying we just need to tell you what happened and I said you don't need to tell me anything because I don't want to get mad. They had planned this and they planned to scare somebody. Well it worked," said Kruse, the victim.

The two 14 year-olds were scheduled to make a court appearance at the juvenile courthouse in Clackamas County at 1:00 p.m. on Thursday.
