BOULDER - A teen accused of planting an explosive device at his school wants to be tried as a juvenile.
Andrew de Bartolome, 16, is being charged as an adult with attempted murder, use of explosives, possession of an explosive and menacing.
He is accused of bringing a device to Centaurus High School in Lafayette May 13, forcing the evacuation of the school and a nearby road for several hours. A teacher found the explosive in a paper bag and took it outside.
During testimony Wednesday, Bartolome's notebook was entered into evidence. Inside the notebook he described himself as being a psychopath and wrote, "I will kill people I don't like."
An FBI agent testified that Bartolome told him the device was meant as a prank and that he built it in such a way that it would not hurt anyone. The suspect said the battery in the device was dead, rendering it incapable of exploding.
However, a sergeant with the Boulder County Sheriff's Office testified that it had all the components necessary to make a bomb.
Bartolome's defense team is asking for a reverse transfer hearing, which will be held October 9. The judge will decide whether the case will remain in adult court.
The judge bound the case over for trial.
