Spurr Elementary School on Joint Base Elmendorf-Richardson from 1968 until 1993. Between 1993 and 1996, he worked as a substitute teacher with the Anchorage School District. Then in 1999 and 2000, he worked in Title 1 after school activities at Muldoon Elementary.Prior to working in the Anchorage School District, Schwantes taught briefly in Southeast and rural Alaska.Detective Vandervalk says there may be additional victims.“Whether or not people want to come forward after this many years, realize every victim deals with a situation in their own way,” he said. “Some people may have put it behind them and it may be too difficult to deal with and they may not want to come forward anymore.”“That’s their own particular choice and what we want to have come out of this is the best possible outcome for the victim.”APD is working with the Air Force Office of Special Investigations to identify other victims who may have attended Mt. Spurr Elementary in the past.
