Earl Leslie Krugel (November 24, 1942 – November 4, 2005) was the West Coast coordinator of the Jewish Defense League. In 2001, he was sentenced to prison on charges of terrorism after he confessed plotting, with the group's leader, Irv Rubin, to blow up the office of Arab-American Darrell Issa and the King Fahd mosque in Culver City, California. In his third year of imprisonment, he was murdered by a fellow inmate, who struck him with a block of concrete.
In September 2005, U.S. District Court Judge Ronald S.W. Lew sentenced Krugel to 20 years in prison. Part of the plea agreement for his sentence demanded that he reveal the names of all JDL activists involved in the 1985 bombing.
The suspect, David Frank Jennings, 30, allegedly attacked Krugel from behind with a piece of concrete hidden in a bag while Krugel was using an exercise machine.
A fitness fanatic, Krugel was using exercise equipment when he was blind-sided between 4 p.m. and 6 p.m. on Nov. 4, 2005.
His main injury was the initial blow to the back of his head, which crushed the left side of his skull and severely damaged his brain and brain stem. But his attacker also delivered multiple blows to Krugel's skull, face and neck, according to the autopsy, which was performed by the Maricopa County medical examiner and obtained by The Journal. Krugel suffered multiple skull fractures, internal bleeding and multiple lacerations to his head, face and brain. The beating knocked out teeth and also fractured one of his eye sockets. Krugel was pronounced dead at the scene.
