The murder happened 33 years ago and Snuka is 73 years old now.
Meeting the number of wrestlers Ive been lucky enough to have met and I can honestly say Ive met damn near all of them of any significance Im sure his brain's fried at that age.
Many of those in prison for murder have brains which are fried. For some reason murder is still considered a crime if the killer's brain is "fried," so long as he knew what he was doing at the time and intended what he did. *IF* he is not now mentally competent to stand trial because he does not comprehend the charges against him and is not able to assist his defense attorney on defending against the charges, the prosecution should not be allowed to go forward, but that hurdle is fairly high.
From the link:
Prosecutors assert Snuka is well enough to stand trial. During cross-examination, they played a video that showed him in the ring as recently as last year — even doing his trademark move, the Superfly Splash, albeit from the second turnbuckle instead of the top. Another video showed him giving an interview recently in which he appeared lucid and in character.That last sentence indicates his attorneys are likely to have real problems with the competency argument. Trial judges are well aware of the fact that more than a few defendants have been known to fake incompetence.
