Some cases are easy, some are tough, this is a tough one that requires something more than excellent police work. What we require is that fortune smile upon us: think positive thoughts, pray for Mike's family, the cop and a visitation by divine karma. We all know what it is to need a break
And that providential fortune
does arrive frequently, solving a number of seemingly hopeless murder cases.
Here's the very common way that it happens and which was very well exemplified in the film,
"The Shawshank Redemption" (when the wrongfully imprisoned banker learns that a newly arrived inmate was a former cellmate of the actual murderer who gleefully bragged
with full case-solvable details about the crime, and the fact that "an innocent banker was convicted of the double murder").
Creatures who commit such crimes
eventually end up in the slammer. Influenced by smuggled-in drugs, alcohol, or long periods of sheer boredom -- they detail to a cellmate or yard buddies some major crimes they got away with. Eventually one of the prison's convicts barters the information directly with authorities (or via his lawyer) in exchange for a radical shortening of his own prison term or a better outcome at an upcoming parole board hearing.

is a glimmer of hope that the case gets solved, justice is served & punishment meted out.
