Since then, Action News has learned that police are negotiating with a man who is threatening to jump from the top of the garage at The D hotel-casino.
They are not allowing cars or pedestrians in the area.
"I got a call this morning to do plumbing work here at Four Queens," says one man stranded for several hours, Jared Tilley. "I went inside, and when I came back out, there was police tape up. I've been out here since 10:15am, waiting to get that truck so I can go out and make some money today."
Family of the man threatening to jump showed up around 3:00pm. Police did allow them underneath the crime scene tape, but it was not clear if they were involved in negotiations.
Earlier this week, a woman was found dead at The D after she fell into a laundry chute. She fell 15 floors to her death. Police do not believe that the woman's death was a result of a crime, but the coroner has not released the official cause of death.
Police have confirmed that the two incidents are not related, and the man threatening to jump Thursday did not know the woman who was found a few days ago.
