McCaffrey, a senior at Massapequa High School, was last seen early February 3 near his home. When McCaffrey didn't come home, his family filed a report with police.
The flag in front of Massapequa High School was flown at half-staff in McCaffrey's memory. The 17-year-old is the second high school senior to die this year. In January, Michael Gruber, a 17-year-old senior, died of meningitis.
