HOUSTON (AP) - Two men were shot and killed during an altercation early Saturday morning in the parking lot of a Houston nightclub.
Investigators say the two men were fighting when one retrieved a gun and shot the other, killing him.
Authorities say a security guard rushing to break up the fight then fired on the gunman, who died of his wounds.
The unidentified men were described only as being in their 20s.
Investigators interviewed several witnesses to the shooting.
They say the guard was questioned and is unlikely to face charges.
