A 30-year-old man was killed in an elevator accident in a luxury Manhattan high-rise Thursday morning. Sam Waisbren's death is sending chills down the spine of people using elevators in offices and apartment buildings across America. As he stepped off the elevator into the lobby, half in and half out, the elevator car suddenly dropped like stone to the basement with the doors still open. Disturbing surveillance video shows him struggling to get out. The moving elevator crushed him to death.
