CHIPPEWA FALLS, Wis.—A 14-year-old boy accused of killing a 10-year-old Wisconsin girl knew the girl and planned the attack, knocking her down and choking her before sexually assaulting her, a prosecutor said Wednesday.
The body of Illiana “Lily” Peters was found Monday along a walking trail just a day after she went missing while returning home from an aunt’s house a few blocks away, sparking anxiety in her small western Wisconsin community before the teenager’s arrest Tuesday.
