BLADENSBURG, Md. (AP) -- Bladensburg police believe carbon monoxide poisoning killed two men found dead in a car.
Police say the two men in their 20s were found Sunday morning in the closed, unventilated car with the engine running.
There were no signs of trauma and authorities say the tailpipe was blocked by ice and snow it's likely that kept the tailpipe from properly emptying fumes and the car filled with the deadly gas.
Authorities say a third person was found under similar circumstances in Greenbelt.
