Carbon Monoxide in NJ Home Sickens 4 Officers, 8 Others

Four police officers were among 12 people sickened by carbon monoxide in a New Jersey home so toxic it left victims convulsing and foaming at the mouth, reports the Associated Press .

Sensors detected dangerously excessive levels of carbon in the home, said Flanders Fire Chief Tyler Wargo. Five people were taken to a New York hospital, including three of the officers, who were released after treatment. Others were treated at the scene.

The names of the injured people were not released, and a hospital spokeswoman said she could not provide information on a patient's condition without their names.

People were lying on the lawn outside the house in Mount Olive when firefighters arrived around 7:30 p.m. Monday.

Wargo couldn't comment on the cause, but officials have narrowed it down to something in the home.

The Morris County Prosecutor's Office is investigating.
