ROCHESTER, N.Y. — A woman and three children were found dead inside a rental car in New York Sunday afternoon and the Syracuse Police Department is investigating the incident as a possible murder-suicide.

A tow truck driver sent to retrieve the overdue rental car found all four people in the car unresponsive and called 911 at 1:47 p.m., Syracuse Police Sgt. Matthew Malinowski said in a news release. The car was parked in a driveway about a mile south of Syracuse University's Carrier Dome.

Syracuse police responded, along with the Syracuse Fire Department and EMS services, Malinowski said in the release. Police Chief Kenton Buckner said during a press conference in Syracuse that a fire department hazmat truck was called to the scene to make sure there wasn't anything dangerous inside the vehicle.

Though the investigation is in its early stages, Malinowski said in the release that evidence "indicates that this was an intentional act by the adult to kill herself and the three children inside."

Police did not release the ages of the children or whether they are related to the woman.

Anyone with information is asked to call the Syracuse Police Criminal Investigations Division at 315-442-5222.
