My guess would be the Marino and Zimmerman murders are related, Nolan is not.
Staying tight-lipped got the MPD nowhere on the Nolan case. I don't know what their strategy is --- there's significant information one can release without jeopardizing an investigation or court case. The release of such information to the public often results in an arrest.
One of the most important questions for me is, were the Marino and Zimmerman murders attempted robberies gone wrong? Is this guy casing out houses to rob during the day and gets confronted, or is he purely a homicidal thrill kill type? There should be some evidence that reveals intent.
Here's a link to a sketch of the Marino suspect. They have a lot of good forensic evidence.
