Texas officials are investigating a murder-suicide.
More from FOX's Paul Stevens:
Authorities saying a Texas teenager killed his mother and two neighbors this past Friday before killing himself.
19-year-old Dylan Westerburg gunning down his mother in their home near Uvalde, Texas, about 85 miles west of San Antonio. He then killed two brothers who lived next door.
Officers arriving on the scene after a witness phone call say they heard a final gunshot they believed was Westerburg shooting himself inside the neighbors' home.
Nearby homes evacuated until Saturday when officers finally found the three men dead. No clear motive determined just yet.
