Investigators believe 21-year-old Jake Thomas Patterson gunned down James and Denise Closs in their home near Barron in October and abducted their 13-year-old daughter, Jayme.
Jayme escaped from a cabin in Gordon, Wisconsin, on Jan. 10, where she said he had imprisoned her. Police arrested Patterson minutes later.
He graduated from high school in Minong, about 10 miles south of Gordon, in 2015 and participated in the quiz bowl team. He has no apparent online presence.
Patterson’s older brother was convicted of sexual assault in 2013, but only a handful of people in Gordon have heard of his family.
