Elevator Traps Deliveryman for 4 Days in N.Y.

Deliveryman Ming Kung Chen is alive and well, but police were confronted with a new mystery: How did he go unnoticed since Friday, trapped and screaming in a Bronx elevator in the very building they had been searching?

Investigators thought the worst when a search of the 38-story Tracey Towers failed to find any sign of the immigrant, who made three Chinese food deliveries before disappearing.

“You would think someone would have realized he was in there,” one police source said.

For four days, police conducted a search that included officers in helicopters checking rooftops and bloodhounds searching nearby Van Cortlandt Park, Woodlawn Cemetery and the Jerome Park Reservoir.

But just past 5 a.m. Tuesday, an alarm sounded in elevator No. 2 and firefighters called to the scene pried open its door and pulled out a trembling, dizzy and dehydrated Chen. He was treated at a hospital for dehydration but was otherwise OK.

“I am very happy people care for me,” Chen said. “I am fine now.”
