The U.S. Attorney's office in San Diego said Monday Michael Lee Blevins and his wife, Danica, were charged with buying a rifle, shotgun and a handgun along with 500 rounds of ammunition using someone else's name.
Prosecutor Phil Halpern said the federal Brady Act prohibits former felons from purchasing firearms. Blevins has a 1988 conviction for manufacturing methamphetamine.
The defendants were released on a combined $1.1 million bond pending further proceedings.
Metabolife was founded in 1989 and markets herbal weight-loss compounds that have come under government scrutiny in recent years because they contained the compound ephedra, which can in some cases cause heart problems, strokes and dizziness.
