From the article:
Two male juveniles, ages 15 and 16, were questioned and searched. A search of the grounds was conducted and a school security guard located an air-soft gun in the parking lot. A knife was not found.
The 15-year-old was serving a suspension and not supposed to be at school. The 16-year-old was not enrolled at the school. They were arrested.
No one was hurt and the school was taken off lockdown.Every gun in the hands of a child must first pass through the hands of an adult.
