Did the search warrant authorize searching all of the homes in the area? Were they searching for weapons, perpetrators, or both? Is there such a thing as a blanket search warrant that allows police to search all the homes in a 6-block area? That seems awfully broad. How could there be probable cause to search individual homes in this manner?
According to one article, police found a shell casing in Jungwirt's front yard. Search my front yard, you will find many cases. Does that mean I shot them? No. But over the years many have perculated up, and some are in near pristine condition. The police fubared this one.
Further, it sounds like the police executed the classic 'blank search warrant'. In a blank warrant, the police use a blank piece of paper as a search warrant, then later go to a judge with what they want to find already filled in. Note that the search has already happened, and the police know what they found already. If it is taking this long to get a judge to sign it, they have a problem.
Someones going to get fired.
