Former Army explosives expert from Overland Park admits to possessing unregistered grenades

KANSAS CITY, Kan. -- A former U.S. Army explosives expert has admitted in federal court that he illegally possessed grenades that authorities say were among a cache of explosives found in his Kansas home.

Forty-two-year-old John Panchalk of Overland Park pleaded guilty Monday in Kansas City, Kansas, to possessing two M-67 fragmentation grenades unregistered to him.

Federal prosecutors say they'll recommend probation.

Panchalk caught investigators' attention in May when police responding to a report of a stolen vehicle at a Parkville, Missouri, self-storage site found storage trailers vandalized. One of them, later linked to Panchalk, contained explosives that included ammunition canisters, blasting caps, C-4 explosives and military grenade simulators.

A search of Panchalk's home uncovered 38 pounds of C-4 explosive, detonation cord, blasting caps, grenade simulators, incendiary devices and the two fragmentation grenades.
