Comment Hans Reiser tried this defense (Score 2) 119
Hans Reiser tried the "somebody else did it" defense. He suggested it was somebody else, but presented no more than vague hints in that general direction suggesting that somebody else had motive. (And, of course, it was all silly hand-waving, since he later confessed and led police to the body.) For Ulbrict's sake, let's hope he has something more substantive.
The police have no obligation to investigate alternate suspects once they've decided on one to charge. If you, defendant, want to blame the crime on somebody else, you need to perform your own investigation rather than merely pointing out the police didn't chase after whomever the defendant thinks would be a more worthy suspect.
I don't know if Ulbrict has some real evidence; if he did, you'd think he would have released it by now.
