The written threat that sent Ridgefield High School students home early Thursday was a reference to a possible school shooting. An image that was taken from inside the girls bathroom at the school shows a written message that appears to read, "FIRST SHOT AT 10 ... GET READY RHS 5\/30\/19." Ridgefield students were dismissed at 9:30 a.m. "Out of an abundance of caution, we are dismissing RHS at 9:30am," the school district wrote on its website. "This dismissal (and the threat) does not affect SRMS. The investigation is ongoing." Ridgefield police released a statement at noon. "To correct any rumors in regards to the ongoing investigation involving Ridgefield High School," Capt. Shawn Platt wrote. "The RPD is actively investigating a written threat (no reference to bombs) that was written in a women's restroom. Out of an abundance of caution the high school was dismissed early. We will update you once we have more information."
