This genius had “how to dispose of a 115-pound woman’s body” in his search history and was on probation so he couldn't leave home except in allotted times with approval. He went to Home Depot during the allotted time to pick up his kids from school, except they didn't have school that day. It's probably standard procedure at this point to search local stores that can provide murder-cleaning supplies, and the police knew exactly when he would have been there.
Big news around here, but how could he be that stupid and leave an evidence trail like that?
Lot of good the mask and gloves did him. >

Think about the sort of people who might do this… not really brilliant planning. 
Intelligent, capable people are rarely going to think that murder is a good solution to a problem, because it isn’t. Of the few intelligent people willing to commit murder, most are doing it in a moment of passion, or out some sort of extremely demented urge like a serial killer’s. It doesn’t matter how bright you are if you do things on a whin, you’re going to make mistakes, and it only takes one to catch you.
Of course there are killers who weigh the pros and cons, carefully plan the crime and execute it, but they’re pretty rare. Most people who get away with murder get lucky, either in terms of victim selection (people who won’t be missed) or law enforcement incompetence. >

Mike Erhmantraut is shaking his head and chuckling to himself. >

But if you call Mike after it is done, he will fix it for 10G. >

SUPER freakin' curious how they managed to track him to the store if he paid in cash and wore a 'disguise' (I use that term loosely here, lol).
My guess is either dumbass had his phone on him the entire time ooor maybe they tracked his vehicle via various CCTV?
