Police are investigating the death of a 55-year-old woman found unconscious with severe head trauma in a Brooklyn brownstone.
Borst's husband, Gaetano Lisco, 51, told detectives that Borst had fallen inside their Cobble Hill apartment Friday afternoon, resulting in a small cut to her head, the law enforcement source said. Lisco said he helped his wife bandage the cut and then he left for work.
Lisco told detectives he called his wife when he got to work, but she didn't answer. Concerned, Lisco said he phoned a neighbor who went to check on her, and found her face down on the kitchen floor, covered in blood but still breathing.
The neighbor called 911 and Borst was taken to Long Island College Hospital, where she later died.
The medical examiner is expected to rule her death accidental, but is awaiting toxicology results before making a final determination, according to a law enforcement source.
Police at one point suspected foul play because of the extent of her injuries, and crime scene investigators returned to the apartment, the law enforcement source said. Detectives retrieved bloody gloves, rags, and a broken vase from an outside garbage can and a broken vodka bottle at the scene.
The source said it appears now Borst had fallen on broken glass and that she may have had old bruises from previous falls, determined after a study of her tissue.
Borst was on medication for depression and anxiety, which likely caused her to bleed out so quickly, the law enforcement source said. Her husband, who was questioned Saturday, told detectives she was a heavy drinker and had other medical issues.
In 2010, there was a domestic incident at the home involving the couple and a report was taken for harassment, the source said.
The medical examiner's office said it is waiting to release its autopsy report until toxicology tests and further tissue examinations are complete.
