Report: Video shows wife purchasing ammo with Orlando gunman

ORLANDO, Fla. – CBS News has learned the wife of the gunman in the mass shooting at Pulse nightclub may have more involvement in the planning of an attack.

Video shows Omar Mateen's wife, Noor Salman, purchasing ammunition and investigators also believe she drove with Mateen to case the club, according to CBS.

Authorities also said Salman might have been in communication with Mateen urging him to not go through with the attack, before it happened and also possibly during the attack while he was on the phone with her in the nightclub.

CBS said it's not clear if Salman's wife knew the extent of Mateen's plans, but there is evidence that she may know more than she originally told investigators.

No other details were immediately available.
