A federal judge in Wichita spared a survivalist any more prison time after his attorney argued the man created explosive devices for defense, not for a possible attack.
Alfred Dutton, of Eureka, was sentenced Monday to time served for unlawful possession of unregistered explosive devices.
The veteran of the U.S. Army and U.S. Marines was convicted in July of having grenades and parts to make destructive devices.
Dutton was initially charged with one count for the grenades and another count for jars of homemade napalm. He pleaded guilty to the napalm count in a deal where prosecutors withdrew the grenades count. But an appeals court overturned the conviction after Dutton had already served 17 months.
Prosecutors then filed a new indictment charging him with possessing the grenades.
