(Carver, MN)  —  A former Twin Cities substitute teacher could serve up to 62 years in prison after he pleaded guilty to a sextortion scheme. Mitchell Ottinger admitted to posing online as a teenage girl to solicit nude photos from boys as young as ten years old.  If the victims refused to send additional images the defendant from Carver threatened to post on social media the ones he received.  A sentencing date for Ottinger has not been determined yet.
