According to Occam's Razor theory, a principle of theory construction or evaluation according to which, other things equal, explanations that posit fewer entities, or fewer kinds of entities, are to be preferred to explanations that posit more. In other words, all things considered, the simplest explanation is probably the correct explanation.
Regarding SK's case. He was last seen by at least two witness' on that fateful day, December 13, 2009. One, new information has been made public suggesting SK approached a neighbor on Savannah Springs Ave. It should be noted this home is the second house from the end of Savannah Springs. New information suggests this neighbor was interviewed by at least two investigators where he states SK asked him something to the effect, " do you want the money."? The second witness is the video itself which captured SK walking by and turning onto Evening Lights. The 6 min gap from arrival to being seen on video is explained by first going to the wrong home. Now, interestingly enough the DiMaggio's lived in the second house from the corner of Savannah Springs and Evening Lights. Mrs. Lee was interviewed (neighbor across the street) where she stated she saw a moving van and the people seemed to be moving out quickly that Sunday. This case starts and ends here. Its simple. This is where SK was last seen by one person and one surveillance system.
In addition, the new public information reveals the casita in which MD lived was trashed inside by MD himself. MD had lived there, convalescing from a bad car accident and on many medications. The police finally interviewed MD in February 2010, I believe. The police reports states his reaction to questioning appeared 'deceptive'. MD has a considerable record of domestic violence and drugs. Red Flag!
In my view, the simple explanation is this. SK was sent there, by whom I don't know. He visited the wrong house, second from the end of Savanna Springs. Getting his bearings, he begins walking to 2260 Evening Lights where he runs into MD. MD on drugs and out of his mind, having heard "money," beats SK to death. Now, the cell is documented to travel north until it dies. Id be interested in knowing the trash collection schedule that week and the route the trash truck takes to dump its load. More importantly however, investigate the property of 2260 Evening Lights with a dog and GPR (ground penetrating radar).
The only way to investigate that property is thru a warrant. This leads me to my thought. Contact a good investigative journalist. Get this back into the public domain. Tell the story of how LE at the time, didn't do such a good job. Give LE another opportunity to investigate; using the new evidence which has been uncovered. There is ample evidence for another investigation here, in my opinion. A good investigative journalist will be the squeaky wheel to get LE back onto the case. 11 years has passed. The public pot will be stirred, perhaps generating tips from current and former co-workers, friends, perhaps MD's family, or even criminals hearing something and wanting reduced sentences. The list goes on.
