Is it true: Vince Foster Death?

No — this has been debunked.

Foster's body was found in Fort Marcy Park, Virginia on July 20, 1993, with a gunshot wound to the head from his own revolver. Five formal investigations have concluded suicide: (1) US Park Police initial investigation (1993); (2) FBI/Fiske initial Senate Banking inquiry (1994); (3) Independent Counsel Robert Fiske report (1994); (4) Independent Counsel Kenneth Starr's three-volume report (1997) — conducted with political incentive to find otherwise had evidence supported it; (5) Senate Whitewater Committee investigation. Medical evidence — gun in hand, gunshot residue on hand, trajectory consistent with self-infliction, depression noted by colleagues in prior weeks — converges. The lack of physical evidence of a struggle, the medication found (low-dose antidepressant), and the location (which Foster had visited previously) are all consistent with suicide.
