(Fremont County, Wyo.) – The files of two teens charged for serious crimes in Riverton have been sealed from the public, likely in an attempt by their defense attorneys to get the cases sent from adult district court to juvenile court.

John Potter, 16, of Riverton, is one of two juveniles charged with the September 2013 Second Degree Murder of David Moss Jr., 25, and the attempted second degree murder of Aleeah Crispin. He and his co-defendant, Santana Mendoza, also 16 and from Riverton, have both pleaded not guilty as adults to the crimes. Mendoza’s file was sealed earlier in December.

Generally, the sealing of a case involving a juvenile corresponds with an attempt by the defense to move the case to juvenile court. However, due to the fact that the cases have been sealed, none of the attorneys involved are at liberty to discuss whether a transfer request has been made. The Ninth District Court Office can only confirm that the cases are sealed.

Additionally, 16-year-old Adrian Joseph Sixfeathers of St. Stephen’s has been charged with Aggravated Robbery, a felony punishable by five to 25 years in prison, in connection with the armed robbery of a woman in the Walmart parking lot in November. He has been bound over to Wyoming’s Ninth District Court in Lander for further proceedings. He has not yet entered a plea. His case, too, has been sealed.
