HARTFORD, Conn. (AP) - A Connecticut prosecutor has decided not to charge the owner of the gun used in the January shooting death of a 15-year-old.

Waterbury State's Attorney Maureen Platt's report says Ethan Song accidentally shot himself in the head at a friend's Guilford home, calling the teen's death "a horrific and preventable tragedy."

Platt says state law "does not support a prosecution" of Daniel Markle, who owned the .357 magnum handgun. The gun was stored with two other weapons in a bedroom closet near where Song was found shot on Jan. 31.

The report says there's no evidence the handgun was stored loaded or improperly. Investigators say juveniles had played with the weapons several times, apparently without Markle's knowledge.

The report also says there's no evidence Song knew the handgun was loaded.
