Duggan also is calling Friday for anyone who can identify people who attacked 54-year-old Steve Utash to step forward so "justice can be served."
Utash accidentally struck 10-year-old David Harris with his pickup when the boy stepped into traffic Wednesday. At least a half-dozen people attacked him as he tried to help the boy.
Utash remains in critical condition.
Terry Emerick is the father-in-law of Utash's daughter. He says Utash has swelling on his brain and still is in "bad shape."
Police Sgt. Mike Woody says investigators were canvassing the neighborhood. The boy is recovering.
