UPDATE
According to CNN, both of Theriot's parents were alive Saturday morning when authorities arrived on scene. The Theriots identified Dakota as the shooter.
"This is probably one of the worst domestic violence incidents I've seen in quite a while," said Ascension Parish Sheriff Bobby Webre.
Apparently Dakota was living with his parents for a short period of time. They had recently asked him to move out and not come back.
Authorities are still looking into possible motives.
