San Antonio police have arrested a 44-year-old man after authorities said he shot and killed his 14-year-old son two weeks ago.

Andres Delgado III was arrested Tuesday on a second-degree manslaughter charge and was being held without bond.

Around 6 a.m. March 14, police received multiple reports of gunshots in the East Side neighborhood. Upon arrival, they found the 14-year-old, Andres Delgado IV, suffering from a gunshot wound to the chest, officials told the San Antonio Express-News at the time.

The boy died after being taken to a hospital.

A search of the home revealed shell casings in every room, the Express-News reported. San Antonio Police Chief William McManus said the father fired multiple weapons, and officers recovered handguns, an AR-15 and a shotgun at the scene.

McManus said at the time that it wasn't clear "what was going through the father's head."

The father claimed the shots came from outside the home, the Express-News reported. However, police told the paper that they couldn't find any shell casings outside.

A 10-year-old girl was inside the home when the shooting occurred, but was uninjured.
