SAN ANTONIO, Texas - May 8, 2008 - A business owner trying to deter what he called repeat burglaries shot and killed another man he alleged was breaking into his carpentry business Wednesday night.

The shooting occurred around 11:30 p.m. in the 3300 block of Roland Avenue on the city's Southeast Side.

San Antonio Police Capt. Chris Andersen said the shooter told police he was "camping out" to catch the suspected thief when he heard a noise coming from the area of his business, which sits behind his residence. Andersen said the man said he saw the alleged burglar inside his fenced-in lawn and hitting his dog with a pipe.

Afraid the man would come after him too, the business owner shot once with a shotgun.

Andersen said the shooting is under investigation but may fall under the "castle doctrine" which allows property owners to use lethal force to protect themselves and their property.

Andersen said the dog was fine.
