Looks like Judge Lama and Judge Wemmer have past practices in criminal law, but it doesn't look extensive and they've only served five or six years as judges. In a small district all four judges handle every kind of case, but I can't see Judge M handing off a complex First Degree Murder case to any of the other three.
Also, I don't think it's appropriate to expect the Chief Judge's subordinates to rule on the propriety of the warrants he approved. If I were BM, I would object to that.
So, even if the three other district judges in JD11 are murder qualified, I'm guessing Judge M will deem them not "available" and ask Chief Justice Boatwright to appoint his replacement. Boatright was a prosecutor in Golden, Colorado before a Republican governor appointed him to serve as a district judge. He has excellent background to make a sound appointment for this case. All MOO, of course.
