A 16-year-old and a 17-year-old were charged with commercial burglary, grand theft, animal cruelty, possession of a weapon on school grounds, and criminal mischief according to officials.

Deputies say after breaking into Lake Weir Middle School, the duo emptied six fire extinguishers, poured out sodas and damaged locks. The teens then stole ten compound bow and arrows from the physical education building, according to deputies.

They used the bows to shoot a pinned up sheep in the back of the school, and proceeded to stab it with a pitch fork, according to deputies.

The animal will make a full recovery.

According to deputies, both defendants admitted to the charges. Local 6 is not identifying the teens due to their age.
