In response to several postings on social media, St. Louis city police sent more than 20 officers to Roosevelt High School Tuesday to protect fans and players at a high school football game. Fox2 News reports that the game between the Vashon and College Preparatory junior varsity teams was played at Roosevelt. The move comes after a 16-year-old was shot and killed after leaving a party attended by teens from Vashon and College Prep. Another 16-year-old was taken into custody after the shooting. Police were alerted to the possibility of violence after noticing several alarming posts on social media. There were no incidents at the game, but police say they will continue to monitor the situation.
