On August 25, 1967, George Lincoln Rockwell, founder and leader of the American Nazi Party (by then renamed the National Socialist White People's Party, or NSWPP), was shot while at the Speedy Laundromat in Arlington, Virginia, near the party's headquarters. A gunman fired two shots from the laundromat's roof; the first missed, and the second struck Rockwell in the chest, rupturing his aorta. Rockwell managed to exit his car and stand briefly before collapsing, and was pronounced dead at 12:02 p.m. Two local barbers chased the fleeing shooter, and about 45 minutes later police arrested John Patler, an expelled NSWPP member, roughly a mile and a half from the scene. The murder weapon, a Mauser pistol belonging to fellow party member Robert Allison Lloyd, was later recovered submerged in a nearby stream.
Patler had a long and volatile history with Rockwell, having left and rejoined the party multiple times, and was formally expelled in March 1967 for insubordination and causing internal dissension. Rockwell had also survived an earlier, unsolved shooting attempt at his home in June 1967, which prosecutors later alleged was carried out by Patler. At trial, prosecutors argued Patler's motive was revenge for his expulsion; the defense argued the evidence was circumstantial and suggested other possible suspects, including party members who stood to gain power after Rockwell's death. Ninety-one witnesses were called. After thirty hours of deliberation, a jury convicted Patler of first-degree murder in December 1967, and he received the minimum sentence of 20 years. His conviction was upheld by the Supreme Court of Virginia in 1970 and the U.S. Supreme Court declined his appeal in 1972. Patler was paroled in 1975, violated parole the following year, served additional time, and was eventually released. He never admitted guilt and later left the neo-Nazi movement, reverting to his birth surname, Patsalos.
Rockwell's death triggered a highly publicized dispute over his body and funeral, including a standoff between uniformed followers and military police at Culpeper National Cemetery, after which his body was secretly cremated by his successor, Matt Koehl. Reaction to the killing was widespread, with responses ranging from Jewish community leaders condemning the violence despite their opposition to Rockwell's ideology, to grief among international neo-Nazi figures who viewed Rockwell as a martyr.
In the years following, various unproven conspiracy theories circulated among Rockwell's followers, including baseless claims of a Jewish conspiracy and allegations that senior NSWPP figures had orchestrated the killing and framed Patler. No evidence has substantiated these theories, and Patler remains the only person convicted in the case. Rockwell's death led to the decentralization of the American neo-Nazi movement, with numerous splinter organizations forming under Koehl's later leadership.
