HACKENSACK — Police found two bodies dead in an SUV parked on a city street on Friday morning and believe they likely were killed by carbon monoxide poisoning.

Hackensack Police Capt. Patrick Coffey said that the 29-year-old man and 24-year-old woman were found in the car in Hackensack Friday morning.

Coffey says there was no signs of a struggle or violence and that police are "leaning toward" a tragic case of carbon monoxide poisoning. He says the investigation will continue to look into any other possibility.

The names of the victims weren't released pending notification of their families.

Coffey says the man is from Hackensack and the woman is believed to be from New York City.

Hackensack Police Director Michael Mordaga said the Chevrolet Tracker with New York license plates was found on Overlook Avenue with a pink handbag on the hood. The road was closed off as police investigated the incident and later towed the car away.

The Daily Voice of Hackensack reported the man and woman found inside the car were having sex and died of carbon monoxide poisoning.

Hackensack police and a spokesman for the Bergen County Prosecutor's Office did not immediately return requests for comment Friday afternoon.
