BROOKLYN - The NYPD is calling the 2010 disappearance of a young Brooklyn boy its most important missing child case.

Police Commissioner Ray Kelly said that investigators have received more than 50 tips related to 7-year-old Patrick Alfrod and that they continue to follow every lead.

Kelly said he's hopeful that the Etan Patz case will help jolt someone's memory on Alfrod, who was last seen at his Starrett City foster home.
