Carlisle Brigham Dead: 29-Year-Old Woman Found Fatally Injured In The Lower East Side (UPDATE)

A 29-year-old woman was found bleeding heavily from a slash wound to the neck in the Lower East Side on Monday.

The Daily News reports Carlisle Brigham was found on the first-floor stairwell of an Orchard Street apartment, where a neighbor said she "had blood on her face."

The woman was taken to Beth Israel Medical Center where she was pronounced dead.

Brigham was reportedly living in the apartment building with a roommate while estranged from her husband Anthony Champalimaud, the son of a prominent Portuguese family.

The couple were married in 2011. According to their New York Times wedding announcement, Brigham worked previously as an intern for the American Museum of Natural History in New York. She is the daughter of James Brigham Jr., who worked as the city's budget director.

Police are questioning Champalimaud, but sources say it appears as Brigham may have fallen off the stairs. No weapon or blood trail were found either.

UPDATE: Brigham's death has been ruled an accident. A representative for the medical examiner said Brigham fell down the stairs and suffered blunt-impact wounds to her head and neck after falling down the stairs.
