Dozens of bodies were slowly removed overnight from a popular Orlando gay club after a gunman sprayed the helpless crowd with bullets in violence that killed 50 people and devastated a city famous for family-friendly theme parks.

When the attacker opened fire in the early hours of Sunday morning, it interrupted an evening of drinking, dancing and drag shows at a club known for tolerance for all people.

Authorities say suspect Omar Mateen emerged, carrying an AR-15 and fired relentlessly — 20 rounds, 40, then 50 and more. In such tight quarters, the bullets could hardly miss. He shot at police. He took hostages.

When the gunfire at the Pulse Orlando club finally stopped, 50 people were dead and dozens critically wounded in the deadliest mass shooting in modern U.S. history.
