A Mexico City man who abandoned his car and tried to walk to safety on a flooded street has been found dead in a subterranean storm drain several blocks away.

City civil defense spokeswoman Macarena Quiroz says the body of Gerardo Ortiz Gutierrez has been identified by relatives. He was apparently sucked into an open manhole cover last week.

Quiroz said Wednesday that workers traced the drain route to the nearest grating meant to filter out refuse. They found the body there but had to break open the drain pipes to recover the corpse.

The 53-year-old man's car stalled late Thursday during rains that flooded city streets.

Mexico City has uncommonly large and complex storm drainage because the city sits in a closed mountain valley with no natural outlet.
