A man from California City was sentenced Monday by a U.S. District Judge for being a felon in possession of firearms, a destructive device, and explosives.

Kenneth William Kirkland, 48, will spend four years and nine months in prison.

On October 11, 2015, Cal City police officers completed a search warrant at Kirkland’s house where they found a 5.56-caliber rifle, a 7.62 x 54R-caliber rifle, and detonators in a yellow metal container, according to court documents.

Several sticks of dynamite and a partially built improvised explosive device was also found.

Nothing was registered in the National Firearms Registry.

Kirkland had been previously convicted in Kern County in 1993 for burglary and was prohibited from having firearms or ammunition. He also had 16 misdemeanor convictions and multiple parole violations.
