A woman plummeted to her death early Sunday morning from the roof of her Midtown West apartment building after she may have been drinking, police sources said.

Elena Gladkikh, 27, fell five stories from the building on 37th Street near 10th Avenue just before 9 a.m., police said. EMS rushed her to Bellevue, where she later succumbed to her injuries.

Gladkikh, a Mary Kay beauty consultant, according to reports, may have been at a bar before the fall, police source said. The New York Post also reported that Gladkikh was found in just her underwear and bra when she fell.

Police believe the fall was accidental, and the medical examiner will determine the cause of death.
