17-year old Pennsylvania boy threatens family with assault rifle and bayonet

A 17-year old boy in Butler County, Pennsylvania, threatened his family with an "AK-type rifle," then tried to hide the weapons.

From an article:

State police in Butler wrote in a news release that they were called to Middendorf Street in Marion about 2 p.m. for a report that a 17-year-old boy "pointed an AK-type rifle" at four family members -- ages 1 to 54 -- and "told them they had 10 minutes to leave the house." 

When someone told the boy that police were on their way, he ran into the woods. Troopers said they found him about three hours later, when he surrendered, unarmed at the edge of the woods. The boy then led troopers through the woods, pointing them to a rifle, a bayonet and six live rounds of ammunition. 

Police said they plan to charge the boy as a juvenile with making terroristic threats, simple assault and recklessly endangering another person.

The article did not state how the boy got the weapons.

Every gun in the hands of a child must first pass through the hands of an adult.
