An 18-year-old woman is facing charges, accused of posing outside a Suffolk County high school with a fake rifle.

Police say Ericka Rodriguez took a selfie of herself holding the imitation rifle in front of Hauppauge High School Tuesday morning, causing the school to go into lockout.

Officials say Rodriguez is a former student of the school.

She was charged with unlawful possession of a weapon on school grounds and endangering the welfare of a child.
