Authorities say a body pulled from the Eastchester Bay in the Bronx Wednesday morning may be that of a Scarsdale doctor who was reported missing Sunday.

New York City police removed the body around 11:30 a.m. near City Island

Mona Shimshi, 55, who was reported missing Sunday by her husband, 61-year-old Dr. Mark Greenburg, had been running errands when she vanished. Greenburg said he reportedly received a one-word text message from his wife's cell phone reading: "goodbye."

Shimshi, who apparently suffered from bipolar disorder and was under psychiatric care, left the couple's Scarsdale home around 1 p.m. Her husband notified police of her disappearance 5 hours later when she failed to return home.

Shimshi worked at Bridgeport Hospital in Connecticut and also practiced endocrinology and internal medicine in the Bronx and Bridgeport, Conn.

Authorities reportedly spotted the car near the Rodman's Neck facility around 9:35 a.m. Tuesday and quickly traced the license plates to Shimshi. According to several people in the area, the car, described as a 2008 gray Honda CRV, had been parked there for several days.

Authorities say when they found the car around 9 a.m. was locked and there was no obvious signs of foul play.

The medical examiner's office will determine the cause of death. Authorities are reportedly treating it as a suicide case.
