Marcus Bell is a detective for the NYPD.
Has an older brother named Andre. He works as a detective for the New York Police Department.
On his way home from a case one night, he is shot at while driving in his car. Marcus ends up crashing into a construction site. The man suspected to be the shooter is found killed, with bootprints of Marcus' shoes found on the site.
