Theory:
Condit paid a "hit person", someone other than Guandique.
My neighbor was a Camera man for one of the local 3 new stations and told me at the time of the investigation into Condit, that he believed Condit looked "guilty as hell". Of course I know that "looking guilty" may not equal guilty.
However, this camerman worked for decades in DC, often covering Congressional scandals, etc. .. so perhaps he was onto something.
Condit's hired hand?
OR were those responsible the same as those who caused the death of Joyce Chiang, a lawyer, whose badly decompoased body was in the Potomac River and whose wallet was found at the banks of the Anacostia rivier in 1999. No charges were filed against anyone Joyce's case.
Joyce's brother Roger late became the executive in Charge at the television show 'America's Most Wanted'.
Joyce Chiang connection:
"In addition to the Congressional intern connection, Chiang had lived four blocks away from where murder victim Chandra Levy would live, in Dupont Circle. Both were young, brunette women of petite stature. The Starbucks where Chiang was last seen was later frequented by Levy. These similarities have led to various theories that both women were killed by the same person, although the Congressman-in-sex-scandal aspect of Levy's case, coupled with the long time that passed before her body was found, led to more media interest."
