The medical examiner ruled Tuesday that the 29-year-old woman found in a pool of blood in a Lower East Side apartment building Monday died from an accidental fall down the stairs.
Carlisle Brigham was found laying face down with blood near her face and neck at the bottom of the first-floor stairwell of 191 Orchard St. Monday morning, police said.
A spokeswoman for the medical examiner said "there were blunt injuries to the head and neck," indicative of a fall.
A 19-year-old neighbor who found Brigham tried to adminster CPR on her.
"From the looks of it, it looked like she tripped, " said Mizanur Raham. "Her bags were just scattered on one corner. She was face-down, like she banged up her head. So it did look like she tripped."
Brigham, who had worked at the Museum of Natural History, was transported to Beth Israel Hospital and later pronounced dead, authorities said.
According to a law enforcement official, friends told police that Brigham was at a wedding Sunday and had been drinking heavily, and that she continued to drink with friends when she returned to New York City.
