UM, WHAT? Officials believe blast that injured man in New York’s Central Park was an ‘experiment.’ “Officials believe an ‘explosive hobbyist’ may have left behind the device that detonated when an 18-year-old man’s foot landed on it in New York’s Central Park on Sunday morning, creating a blast that resulted in a severe leg injury for the man. . . . O’Connell and bomb squad commander Lt. Mark Torre said it was not unusual for individuals to create “homemade” fireworks as Independence Day celebrations approached. Officials were scouring the park for other, similar devices, but there was no evidence more than one existed.”

UPDATE: More here. The FBI is now reportedly investigating.
