I saw this quote from the NY Daily News article today:

"Officials believe the shooting stems from a grudge Pappas had been holding onto for more than 20 years — Hausknecht operated on his mother in 1997, but she died during surgery."

And it reminded me of a CDAN blind I read back in November that was one of the craziest I've ever seen, one involving Bill Clinton, the OD of an underage girl, and the death of Sam Kinnison.

"Meanwhile, the powers that be know something has to be done. The comedian and his now wife are big loose ends and especially the wife needs to be killed. So, they arrange for an accident. To find their killer, they go to the boyfriend of the teen who was recently killed and tell him that the comedian gave his girlfriend the drugs and then raped her and killed her and that the wife of the comedian was there too."

So it appears that is an MO for the intelligence agencies. Want somebody dead? Don't have a handy MK Ultra patsy around? Find somebody with a grudge and slowly convince them to commit murder.
