SAN ANTONIO -- A strange noise reportedly led a local family to find an accused sex offender hiding under their stairs.

According to an arrest warrant, Leonard Trevino was under a flight of stairs at a home in the 700 block of Virgin Oak when the family heard their dog barking.

Trevino emerged with a gun and demanded to be let into the house on Nov. 10, according to the warrant.

The mother and son living at that address reportedly fought with the armed suspect, and the son shot Trevino in the face.

Police said Trevino is also a suspect in a child indecency charge in connection with the same family.

He is also now charged with aggravated assault with a deadly weapon and was taken to a local hospital for treatment.
