Timothy Jackson maintained his innocence Tuesday and asked Wayne County Circuit Court Judge Michael Callahan for mercy prior to his sentencing. Callahan told Jackson the crimes in which he was convicted were "heinous" and "unspeakable."
Jackson was found guilty last month of multiple counts of first-degree criminal sexual assault.
Authorities said the girl was 11 when the sexual assaults began at Abundant Life Church, and continued in 2009 and 2010. The girl reported the rapes in August 2010.
