(NECN/ABC) - A Massachusetts father is not giving up hope in the search for his daughter, who went missing in the Haitian earthquake. Leonard Gengel of Rutland arrived in Haiti Saturday to search through the rubble of the Hotel Montana. That's where his 19-year-old daughter Britney was last seen when the quake struck twelve days ago. Gengel was originally told that Britney was safe. But then received word she wasn't. Britney Gengel is one of six people from Florida's Lynn University still missing. Leonard Gengel has asked the US government to guarantee that every American in the hotel be accounted for and returned home.
