A construction worker was found dead inside an elevator shaft in a Hell's Kitchen building Sunday morning, officials said.

Police officers were called to a building on 10th Ave. and 41st St. shortly around 7:14 a.m.

They found Steven Simpson, 53, between the elevator and the elevator shaft on the fifth floor, according to officials.

It is not clear how long Simpson had been there.

Emergency medical crews that responded pronounced him dead at the scene, the city police department said.

Investigators believe he suffered a cardiac arrest, but the medical examiner will determine his exact cause of death.
