It happened around noon at the Villas on the Lake resort on Texas 105 in Montgomery.
A 12-year-old boy was pinned under a Chevrolet Tahoe when emergency responders arrived.
A representative at the resort told The Conroe Courier that the boy's aunt came into the lobby screaming for a jack to lift the SUV off him. She said her nephew ran over her other nephew.
