Marty Chonks

In the video game, Grand Theft Auto III, Marty Chonks owned the Bitch 'n' Dog Food Factory in the Portland borough of Liberty City. His wife had an extramarital affair with a man named Carl before she was killed by her own husband, Marty Chonks. In the end, Carl killed Marty and took over his dog food empire.

Marty Chonks is assumed to have started the business after 1998, as the factory belongs to someone else in the video game Grand Theft Auto: Liberty City Stories. If Grand Theft Auto IV was to take place in 2007, then Marty's old dog food factory will definitely belong to Carl, who might either keep it as a dog food factory or use it something else (as long as its kept industrial, as per the Liberty City zoning laws). It is assumed that Marty Chonks is a lifelong resident of Liberty City, as he is never seen in Grand Theft Auto: Vice City or Grand Theft Auto: San Andreas.
