STAMFORD — Since he left Connecticut during a snow storm in February 2001, Franz Barthelemy fell in love, fathered four children, opened up a store in Port Au Prince, Haiti and did security work for the Red Cross after the devastating earthquake there in 2010. His family insists that over the past 16 years the Westhill High School graduate lived a model, law-abiding life on the Caribbean island under his real name until his past caught up to him about a month ago.
