Father's Day without Matthew

Matt Russo was born with Down syndrome and diagnosed with leukemia at age 2, before he died last year at age 7. He had endured leukemia and chemotherapy for half his life. Matt's ordeal inspired his father Phil Russo, 48, to write a book, "Matt Taught Me," to give parents insight from his struggle. Phil credits his father Guy Russo, 72, of East Northport, with teaching him life lessons that helped him survive the ordeal. (Credit: Barry Sloan)
