Nearest simile would Vice Foster's suicide. How much was spent on that investigation. Can't believe it was all that much, from what I recall, but then, I wasn't following politics all that closely then.
There is quite a list of people who in one way or another were associated with the Clintons who have died under questionable circumstances.
I found a snopes article that talks about the various other media and compiles a list of people reported over the years.
Here are some of the people below... there is quite a few more.
I'm not alleging the Clintons had anything to do with anything by this post. Other than it is sure might be unlucky to be around them.
James McDougal - Clinton's convicted Whitewater partner died of an apparent heart attack, while in solitary confinement. He was a key witness in Ken Starr's investigation.
Mary Mohane - former White House intern gunned down in a coffee shop. Nothing was taken. It was suspected that she was about to testify about sexual harassment at the White House.
Vincent Foster - former White House Counsel, found dead of a gunshot wound to the head and ruled a suicide. He had significant knowledge of the Clintons' financial affairs and was a business partner with Hillary. If the Clintons are guilty of the crimes they are accused of by Larry, Vincent Foster would have detailed knowledge of those crimes.
C. Victor Raiser, II - former National Finance Co-Chairman of Clinton for President, and Montgomery Raiser, his son. Both died in a suspicious private plane crash in Alaska. No cause determined. Raiser was considered to be a major player on the Clinton team.
Paul Tully - DNC Political Director, was found dead in a Little Rock hotel room. No cause was ever determined and no autopsy was allowed. Tully was a key member of the damage control squad and came up with some of the Clinton strategies.
Ed Willey - Clinton fund raiser. Found in the woods in Virginia with a gunshot wound to the head. Ruled a suicide.
Hershell Friday - Clinton fund-raiser. His plane exploded.
Jerry Parks - former security team member for Governor Clinton. Prior to his death he had compiled an extensive file on Clinton's activities. His family had reported being followed and his home broken into just before being gunned down at a deserted intersection.
John Wilson - former Washington D.C. council member. Had ties to Whitewater. Died of a very suspicious hanging suicide.
Kathy Ferguson - former wife of Arkansas State Trooper Danny Ferguson, the co-defendant with Bill Clinton in the Paula Jones lawsuit. Found dead in her living room of a gunshot wound to the head. Ruled a suicide. Interestingly, her packed suitcases seemed to indicate she was about to go somewhere.
Bill Shelton - Arkansas state trooper and fiance of Kathy Ferguson. Allegedly committed suicide by shooting himself at her grave.
Dr. Donald Rogers - dentist. Killed in a suspicious plane crash on his way to an interview with reporter Ambrose Evans-Pritchard to reveal information about Clinton.
Stanley Huggins - lawyer investigating Madison Guaranty. Suicide. His extensive report has never been released.
Suzane Coleman - reportedly had an affair with Clinton. Was seven months pregnant at the time she was found dead of a gun shot wound to the back of the head, ruled suicide.
Paula Grober - Clinton's interpreter for the deaf. Traveled with Clinton from 1978 until her death in 1992 in a one-car accident. There were no witnesses.
