GRYGLA - A 59-year-old Grygla man faces federal charges for sexually abusing girls while on the Red Lake Indian Reservation.
On Monday, Dean Earl Wilkens was charged with one count of aggravated sexual abuse of a child under the age of 12 and one count of abusive sexual conduct.
Those charges are in addition to three counts of aggravated sexual abuse of a child under the age of 12. Previously Wilkens was charged with those crimes.
A news release from the U.S. Attorney's Office said Wilkens engaged in sexual acts with three girls between December 2008 and December 2011.
The FBI learned of one of the assaults after a victim disclosed the abuse to a school official.
If convicted, Wilkens faces a potential maximum penalty of life in prison on each count.
