Tragedy struck the upscale neighborhood of Westchester, New York, as a prominent oncologist, Dr. Krystal Cascetta, allegedly took her own life and that of her four-month-old daughter in what authorities are calling a murder-suicide.

The shocking event has left neighbors and the medical community stunned, shedding light on potential warning signs in the weeks leading up to the incident. According to a neighbor, Bob Stuart, police and ambulances had visited the Cascetta residence on multiple occasions throughout the summer.

The exact reasons for these visits remain unknown, adding a new layer of complexity to the tragic event. Stuart and his wife, Betsy, described the couple as private individuals who kept to themselves. In fact, many neighbors were unaware that Dr. Cascetta was even pregnant.

The incident occurred on Saturday morning when Cascetta, with her parents present in the home, entered her baby's room and allegedly shot the child before turning the gun on herself. A 911 call was made from within the residence, with the caller reporting hearing a loud noise resembling a falling object followed by a gunshot.

Upon arrival, first responders discovered the lifeless bodies of the doctor and her daughter. Authorities have affirmed that this was a clear-cut case of murder-suicide, but the motive behind the tragic act remains unknown. Friends, patients, and colleagues took to social media to express their heartbreak over the loss of Cascetta, an esteemed hematologist-oncologist at Mount Sinai Hospital.

Cascetta was described as compassionate, dedicated, and a true professional by those who knew her well. The Mount Sinai community expressed its deep sorrow and extended sympathies to Cascetta's family and loved ones. The hospital highlighted Cascetta's contributions to breast-cancer research and her commitment to providing excellent care for her patients.

Throughout her career, Cascetta's passion for medicine was evident, with her husband stating that being a doctor was in her DNA. As the investigation into this tragic event continues, the local community and medical professionals mourn the loss of a talented and compassionate doctor who touched the lives of many.
