A prominent New York City cancer doctor killer herself and her baby at their West Chester home Saturday morning in what police believe was a murder-suicide, reports said.

Dr. Krystal Cascetta, 40, a Hematology-Oncology specialist at Mount Sinai Hospital, died from a self-inflicted gunshot wound around 7 am after apparently shooting her child, according to ABC 7.

The incident happened at her home in Somers.

It remains unclear how old the child was.

“A preliminary investigation revealed that at approximately 7:00 a.m., Krystal Cascetta entered her child’s room and shot her baby and then turned the gun on herself,” state police said in a statement.

“The scene is consistent with a murder/suicide.”

Cascetta graduated from Albany Medical College, according to her biography on the Mt. Sinai website, where she was given an award for the compassion she showed when dealing with patients.

She completed her residency at Hofstra North Shore LIJ School of Medicine at North Shore University Hospital, where she earned a similar award.

At Mt. Sinai, Dr. Cascetta specialized in breast cancer research.

The hospital did not respond to requests for comment at the time of publication.
