The police didn't need MK for the sketch, the milkman, the alleged security video taken a few minutes before the kidnapping, the hospital security man, Moul, and possibly the guy that said he saw him a few days after the kidnapping (though his story was discredited) could have combined for a pretty good picture, they were all the same description and I think the same person, 5'8", white, dark hair, clean shaven, wearing a white baseball hat, 30's, etc.

Excellent point, unless the police have already learned that not all of the pieces fit. We already know that Moul was too far away from whoever picked up Ricci to identify him.
