Michele Garcia and Frank Garcia
Robert Oswain was one of hundreds of NYPD officers who patrolled the World Trade Center site shortly after September 11, 2001.
In 2010, Oswain died from a rare form of cancer that his family believes was caused by exposure to toxic dust at Ground Zero.
His parents, Michele and Frank, came to StoryCorps to remember him.
Recorded on December 5, 2010.
