That hose has been bugging me. If the hose was lying on the ground at 8:44, then why would AM bother coiling it after hosing himself off? He would have just left it where it was. Why waste time coiling it? I think that Paul or Maggie must have coiled it kinks and all before AM shot them. Then how did AM clean himself off? He probably did not use that hose at all. I noticed there was another hose across from the kennels that he could have used, or he could have just turned either hose on with it still being coiled to wash his hands off. He then would have taken off his shoes, laid a sheet or towel in the back of the suburban, where he placed his blue shirt, shoes, guns, and MM's phone. He drives to the house, takes off his pants and underwear, showers quickly, leaves the wet towel and pants on the floor, changes into the white shirt, accidentally dropping one just like it on the floor, puts on the shorts, slips on some new shoes, starts to make the fake calls/texts to Maggie with the phone he had accidentally left in the house, drives to Almeda, ditches MM's phone, quickly hides the guns, shoes, shirts before Shelley knows his car is there, parks out front, visits mom for 20 minutes, speeds back to Moselle, and calls 911. This fits my "he snapped" theory, which I think is the most plausible one. I believe he really loved his family and could not have planned this. It was much too brutal. Something set him off with the combination of events that day and something PM or MM must have said at the wrong time and place that was his last straw. Problem is if he snapped, he wouldn't have had time to go get guns from the house, so (I know it's a stretch) it is possible Paul might have had them in the side by side that PM and MM took to the kennels. Paul would have convinced Maggie to ride with him. After AM came to his senses after the murders, he quickly took action to cover it up. AM was good at thinking on his feet and, as we all know, lying. I know there's a lot of what ifs in this theory also, such as the ditching of the phone at the same time as the suburban starting up, and the time it would have taken AM to do all those things, but 16 minutes is longer than you think. I wonder if any agent recreated the time it would have taken AM to do all those things, or have I just watched too many Columbo episodes?
