Thomas Casoria was looking forward to Oct. 13. That is when the 29-year-old firefighter was getting married. Casoria is believed to have perished searching for survivors in Two World Trade Center. For the past three years, Casoria had been with Engine Co. 22 on the Upper East Side of Manhattan. A graduate of Holy Cross High School in Flushing, Casoria was an all-star in football and baseball there. He lived in Whitestone and enjoyed traveling to play in sports competitions such as a recent game in Detroit with the fire department's softball team. “He had cousins and many friends who were firefighters,” said his father, Carlo Casoria. “It's something he always wanted to do for many years.” He is survived by a brother, Carlo, who is also a city firefighter, and a sister, Janine.
