A 4-year-old boy was hurt Tuesday when he fell into a sinkhole on Detroit’s east side while playing. Michelle Edwards said her grandson was riding a tricycle near Young Street and Mac Crary Avenue when the front wheel came off, sending him tumbling into the hole. "I ran down here and he said, "Grandma, I can’t move my legs.’ I called 911 because I didn’t want to move him," Edwards said.
