Joseph Adams Milteer (February 26th, 1902 - February 28th, 1974) was a right wing extremist and racist.
Involvement in the JFK assassination?
On November 10th, 1963, Miami Police provided a tape to the FBI and the Secret Service made by an informant who had infiltrated a far-right group. On it was a recording of Milteer saying that there was a plot to kill President Kennedy "From an office building with a high-powered rifle...They will pick somebody up within hours afterwards...Just to throw the public off."
On the day Kennedy was shot in Dallas, a man fitting Joseph description was seen and photographed on Houston Street looking at Kennedy.
