And it was a citizen with a firearm who made the perp drop his weapon.
Reddit has a poster saying one of the victims is 2 years old
Actually, that citizen, a neighbor, had a shotgun and engaged the shooter as he left the church.
He may have fatally wounded him, becasue the suspect crashed his SUV at the Wilson/Guadelupe County line, and was found deceased when the police got to the vehicle.
There were other weapons in the vehicle also.
