Las Vegas Police Lt. Ray Steiber says the shooting happened at about 8:30 p.m. Friday at the Excalibur hotel-casino.
Steiber says a man shot a woman near the front entrance of the high-rise hotel. He then turned the gun on himself and was found dead at the scene.
Steiber says the woman was transported to a local hospital, where she was pronounced dead.
Neither the gunman nor the victim was identified. However, Steiber says the woman worked as a vendor at the hotel's concierge desk, where tourists can get show tickets and restaurant reservations. He says the relationship between the shooter and the victim wasn't immediately clear.
No one else was injured.
