Marquez, 24, bought the .223-caliber DPMS model AR-15 and the Smith & Wesson M&P15 assault-style rifles used in the shootings at the Inland Resource Center on Dec. 2.

The shooters, Syed Rizwan Farook and his wife, Tashfeen Malik, were killed in a confrontation with police a few hours later.

U.S. Magistrate Judge David Bristow sided with prosecutors in Riverside, California, saying that while Marquez didn't appear to be a flight risk, the charges that he conspired with Farook to commit terrorist acts in 2011 and 2012 indicated that he could be a threat to the community.

If he's convicted, Marquez could face 15 years in federal prison on the terrorism charge and 10 years each on two other charges: making a false statement in connection with the acquisition of the rifles and immigration fraud for what authorities said was a sham marriage to a distant relative of Farook's.
