TUMWATER, Wash. - A 14-year-old Tumwater boy was arrested after police said they found weapons and ammunition at his home.

The boy allegedly made threats to harm himself and others at Black Hills High School. He faces potential harassment and weapons charges.

According to Tumwater Police, two other students heard of the suspect's intentions and spoke with police, leading to the arrest.

The boy was arrested Monday after police said they found two weapons in his bedroom along with ammunition, gun powder and fireworks.

Another gun was found in the home, according to Thurston County juvenile prosecutor Wayne Graham.

Graham said the boy had a fascination with the school shootings at Colorado's Columbine High School.

He had done a lot of research in regards to the Columbine shootings, said Graham. He had indicated he admired the two men involved in that.

During a court appearance Tuesday, the boy's mother pleaded for her son to be released.

My son has had depression issues and I believe that this was just a cry for help and attention, Maya Terry-Blackburn told Juvenile Court Commissioner Indu Thomas.

The teenager's grandfather told KING5 the boy's father gave him the guns for grouse hunting. He added the young man is quiet with slipping grades, but called the charges unbelievable.

Thomas ordered the boy held in custody at least until he undergoes a mental health evaluation.
