A New York City cancer doctor killed herself and her baby in her home early Saturday morning, according to police.

Dr. Krystal Cascetta, an oncologist at Mount Sinai Hospital, shot her baby and then herself at their home in Somers, a town about 50 miles northeast of New York City, around 7 a.m. on Saturday, New York State Police said.

Authorities are investigating the incident, according to information from state police, which said that “the scene is consistent with a murder/suicide.”

It is unclear how old the baby was or whether anyone else was in the home at the time.

Trooper Steven Nevel said that he was not permitted to release more details on the circumstances of the incident, but said: “We know, 100%, without a doubt, that it was a murder-suicide.”

Nevel said the 911 call came from someone inside the residence, who, upon hearing the first gunshot, rushed to the baby’s room, thinking something had fell. The unidentified caller heard a second gunshot before getting to the room, where they broke down the locked door and found the dead mother and baby inside, Nevel said.

According to Mount Sinai’s website, Cascetta treated breast, bone, gynecological and gastrointestinal cancers. She worked as site chief of the Mount Sinai Queens Infusion Center, a treatment center for cancer and blood disorders, and as an assistant professor of medicine within the Division of Hematology and Medical Oncology at the Icahn School of Medicine at Mount Sinai.

Cascetta graduated from Albany Medical College, where she was inducted into a national honor society “for demonstrating excellence in humanistic clinical care, leadership, compassion and dedication to service,” according to her Mount Sinai webpage. She had also been studying for a Master of Health Administration degree at Cornell University as of 2022.

A spokesperson for Mount Sinai Health System said in a statement provided to NBC News: “The Mount Sinai community is greatly saddened by the tragic loss of a Mount Sinai Health System doctor and her child. We extend our deepest sympathies to Dr. Cascetta’s family, friends, colleagues, and patients.”
