Mark Essex gunned down 19 people, including 10 police officers. From trutv.com:
In the cockpit of the helicopter, Pitman was aware that the policemen had discovered the sniper's hiding place. He eased the big helicopter away from the roof as if he were pulling out. It was a high stakes game of cat and mouse.
With the pipe under him split open and the helicopter again flying away, Essex dropped to the floor of the alcove and picked up his rifle. He charged out onto the roof to fire another couple of parting shots at the retreating aircraft. Then the searchlight hit him.
After dropping away from the hotel, Pitman had reversed direction and slipped back over the building. He swept his searchlight across the roof. "I saw him come out of the dark," Pitman says. The gunman was caught out in the open, 30 feet from the Gravier cubicle. The sniper snapped his rifle up to his shoulder. Pitman saw a flash and a red-hot ball rocketing up toward him. The gunmen's round slammed into the transmission housing just above the cockpit. Pitman knew the helicopter had been hit. He didn't know how badly or even how long they could stay in the air, but he held the big bird steady over the hotel as the policemen in the back adjusted their line of fire. They were 10 feet off the roof and less than 50 feet from the sniper.
"We were looking eyeball to eyeball at him," Saacks says. With a fresh magazine in his M-16, Saacks opened fire. "I just walked the bullets right into him."
When Pitman's searchlight finally caught Essex out in the open, the elusive enemy that the police had been chasing for a week was finally exposed. Policemen who'd crouched for hours in open windows and on rooftops all around the Howard Johnson's started shooting.
Mark Essex's body convulsed beneath the fusillade of police bullets and collapsed onto the roof. His Ruger .44-caliber Magnum carbine lay beside him, broken into pieces by the hail of gunfire.
"He was hit a number of times," recalls Pitman, in a bit of understatement. An autopsy later revealed Essex had been struck by more than 200 bullets.
"The guy was so shot up he had to be picked up with a scooper," says Eddie Rantz, who was perched on a nearby building, armed with a .30-caliber carbine, and who took part in the volley of shots that finally brought Essex down.
