We are not releasing the name of the suspect because of his age.

A statement released Friday by the Hillsborough County Sheriff's Office, the Hillsborough County State Attorney said they found "insufficient evidence to rebut (the suspect's) claim of self-defense."

However, the suspect and his mother, Heidi Quinn, 51, of Valrico, were arrested and booked into the Orient Road Jail on Friday on other charges.

Heidi Quinn faces two counts of tampering with physical evidence.

The teen suspect faces charges including possession with intent to sell, drug trafficking, possession of drug paraphernalia and unlawful possession of a firearm.
