Enrique Marquez, the former neighbor of the San Bernardino shooters who is accused of buying the rifles used in the attack, pleaded not guilty on Wednesday, ABC7 reported.
Marquez faces multiple charges in a federal indictment accusing him of conspiring with one of the shooters and to provide material support to terrorists, the news station noted.
Prosecutors stress there is no evidence at this point that Marquez knew about Syed Farook and his wife Tashfeen Malik's plans to open fire at the Inland Regional Center in December.
However, they did say Marquez provided them with their assault rifles and that his failure to warn authorities about his purchase of the guns had deadly consequences, according to ABC7.
