AUBURN â It took a month of sleuthing, but a man wanted on a Level 3 felony rape charge in DeKalb County has been arrested in Kentucky after nearly a year on the run, police said. Christopher F. Johnston, 30, was arrested by Kentucky State Trooper Mark Spencer at a residence in Thelma, Kentucky, late Friday afternoon. Johnston is going through the extradition process so he can be brought to Indiana to face the charge, according to the Indiana State Police. A no-bond warrant was issued for Johnston on the rape charge on Feb. 27, 2020, by DeKalb County Superior Court II Judge Monte Brown.
