Authorities say they had not answered any previous domestic violence calls at the house.
"At this time, it is still under investigation," said Harris County Constable Pct. 4 Lt. Ronnie Glaze. "It's not clear what started the domestic disturbance. We just know it's a fight between family members."
Deputies used a K-9 unit and found the suspected shooter in a nearby home. He's now facing charges of aggravated assault with a deadly weapon.
