Jennifer Morales of Manhattan says it's believed her father, George Morales, died of a heart attack.
Morales said she had last heard from her dad in early May. Morales said she had contacted police; but police say they have no report on record.
A city marshal found the body of George Morales on Wednesday while trying to tow the minivan from beneath the Brooklyn-Queens Expressway overpass. Parking tickets and dust covered the vehicle.
