POMPANO BEACH, Fla. (AP) - Authorities say a South Florida teen who accidentally shot his younger sister in the leg has been charged with lying to detectives.

The Broward Sheriff's Office reports that the 14-year-old boy was charged Thursday with tampering with evidence and giving false information to law enforcement.

The boy had initially told investigators that he found the handgun in his backyard shortly before shooting his 10-year-old sister Wednesday night. Detectives later learned that he had had the gun for several months.

The boy's parents said they did not know he had been hiding a gun. The girl was taken to a Fort Lauderdale hospital Wednesday night and released several hours later.

Authorities still believe the shooting was an accident.
