KEARNEY - A former Kearney man will be in federal prison for the next 81/2 years for possessing a homemade machine gun.
Aaron Lawless, 24, of Gothenburg, formerly of Kearney, was sentenced Friday in U.S. District Court with the weapons violation by Judge Richard Kopf.
A Nebraska State Patrol trooper on Interstate 80 near Odessa stopped Lawless in November 2008 for traveling 81 mph in a 55 mph construction zone. As he was pulling over to stop, Lawless threw a marijuana pipe out of the vehicle. When the trooper interviewed Lawless, he found two machine guns, several other weapons and weapon parts inside the car.
Lawless' passenger, Richard Canfield, 32, of Overland Park, Kan, owned the guns, but neither gun had a serial number or was registered to Lawless or Canfield with the National Firearms Registration and Transfer Record.
Canfield has been convicted in federal court of knowingly possessing the machine guns, three .22-caliber rifles, a 12-gauge shotgun, a .22-caliber pistol, three silencers, 7.62 mm-rifle, the lower receiver from an AR-15, and a 9-mm pistol frame.
Sentencing will be in February. He faces 10 years in federal prison and a $250,000 fine.
Unlike the state Department of Corrections, which offers defendants parole, federal prison doesn't.
According to federal court records, Lawless admitted to shooting the machine guns near Cozad earlier on Nov. 25, 2008, and knowing the guns were homemade and had no serial numbers. Lawless pleaded guilty to the charge in September.
A press release from federal court said Lawless was found to have both post traumatic stress disorder and bipolar disorder, was also placed on supervised release for three years and was ordered to enroll in an in-patient treatment program for PTSD.
