Marvelous! Like an ordinary criminal trying to dispose of the body.
He may have thought no body, no crime? but that doesn't work very well when said crime is filmed start to finish and published on Youtube...
Judging by the Hans Reiser case "no body, no crime" doesn't work at all.
there's something to be said about people instinctively distrusting the socially inept: just look at all these modern "catch a pedophile" outfits, where losers are baited by impossible situations into ruining their life.
...several days after the killing (per the testimony of an officer)[0]. reading books about homicide investigation is not illegal, and certainly not suspicious enough to convict beyond a reasonable doubt.
I believe a more charismatic person could have talked his way out of it. At the very least the first impression wouldn't have been "eccentric unsympathetic computer guy, russian mail-order bride, he probably did it".
