The body of a 70-year-old Brooklyn cab driver lay undiscovered for three days after snow from last weekend's storm encased his livery car, making it impossible to see inside, police said.

The man, whose name was not released pending family notification, was discovered around noon Wednesday on Harway Avenue in the Gravesend (search) section of Brooklyn (search), near where he lived, said Sgt. Kevin Ferrell, a police spokesman.

It appeared that he died of a heart attack shortly after parking his car on the street sometime Sunday, police said, as a winter storm was dumping nearly 18 inches of snow on Brooklyn.

Snowplows then pushed banks of snow against his car, blocking views inside.

The man's body was discovered after Wednesday's above-freezing temperatures melted the snow. The medical examiner's office would determine the official cause of death.
