The boy fell into the river from a boulder he was standing on during a family photo shoot.
His parents jumped into the cold water to rescue him, but were unable to reach him before the current carried him away.
Search and rescue teams from several agencies sent divers into the icy water for three days, mainly concentrating on a seven-block area from 24th Street to 17th Street. By Tuesday, the water was moving too quickly and searchers switched to kayaks.
