SACRAMENTO, Calif. (AP) — A convicted felon has been indicted by a federal grand jury after authorities discovered machine guns and a hand grenade at his property.

Roseville Police spokeswoman Dee Dee Gunther says a motorcycle gang investigation in January led police to search a home and storage locker in Lincoln, about 30 miles northeast of Sacramento, belonging to Eric Smith.
