1973: A week after shooting and killing two police officers in an attack on the New Orleans Police Department, Mark Essex fatally shoots another seven people and wounds eight more at a Howard Johnson's Hotel. Using a military helicopter and snipers on nearby buildings, police are later able to shoot and kill Essex, who had taken cover in a concrete cubicle on top of the hotel's roof.
