The teenager who lost his foot after a July 3 explosion in Central Park said Monday that he can now walk again and thanked the many “compassionate people” who donated funds that allowed him to buy a prosthetic leg. Connor Golden, 19, said the online fund account has raised more than $70,000. “I cannot find words that adequately express my gratitude for how much hope and support you all have given me,” he said, adding that he’s been able to pay medical bills and recovery costs, as well as the prosthetic. “It is a beautiful thing to see how many people are by my side when a tragedy like this strikes,” Golden said. “Friends, family, and compassionate people I have never met—including fellow amputees, New Yorkers, fellow students and alumni, and those having a shared interest in music or scouting—have decided to help. I want everyone to know how much your support means to me.” The Virginia Eagle Scout stepped on explosives that were left behind during the run-up to the Fourth of July holiday.
