Good guess. I am guessing this case is in the first quarter with lots more to come out. According to the arrest affidavit, the first cell tower warrant was issued Dec 23.
Long before his arrest, I stated that the killer likely kept the weapon or stowed it somewhere he could pretty easily retrieve it. Since it came out that he left his sheath at the crime scene, I'm a little less certain of that, but would not be surprised if they found it, maybe even in his apartment.
The surveillance team that was on him in PA caught him sneaking out of mommy and daddy's house at 4:00 a.m. to dump trash in the neighbor's trash can...which they retrieved. Criminal mastermind Slow-burger wasn't quite as brilliant as he gave himself credit for being. I love the fact that Moscow PD's lead detective on the case is a young, relatively inexperienced 26 year old. That has to just humiliate Slow-burger to no end. I'm still predicting:
1. Slow-burger will be offered a deal to plea in exchange for taking the death penalty off the table and refuse. Of course some of that is contingent on prosecution's consultation with the families, but I think he's too stupid and arrogant to plea.
2. If it does go to trial, he will go against his attorney's advice and insist on testifying just to show everybody how smart he is, and will torpedo himself (even further) on the stand.
