(Prior Lake, MN)  —  Prior Lake School officials are investigating after a high school student posted a racist video on social media.  Police say the video, which was posted Monday, shows a female student on screen, as well as the voice of another student offscreen and both are using racial slurs.  At one point in the clip, both suggest a student of color take their own life, all while laughing.  School officials issued a statement calling the video “disturbing” and “racist.”  The Savage Police Department says they are working with administration to investigate the incident.
