MOBILE, Ala. (AP) -- An Alabama man charged after he showed up at a Sunday church service armed with several guns and wearing military fatigues has been deemed unfit to stand trial.

Reports say U.S. District Court Judge Kristi DuBose on Friday ordered 29-year-old Robin Lee Hernandez to be treated at a prison medical facility for up to four months. Then the judge will reassess whether Hernandez can understand the charges he faces.

Authorities say Hernandez of Daphne had two assault rifles, a loaded handgun and a knife when he came to Fairhope Church of Christ during Sunday services last July, a day after delivering a threatening manifesto to the pastor.

Hernandez was charged with being an unlawful drug user in possession of a firearm. Prosecutors say he had been smoking marijuana.
