A former Michigan City police officer will spend decades in prison after he was convicted of repeatedly raping an intellectually disabled woman.

a judge sentenced Thomas Jackson to 36 years behind bars.

He was found guilty of three counts of rape. The victim was in her early 20s at the time, but her mental capacity is that of a 10- to 12-year-old.

Prosecutors charged Jackson with four counts of rape in April 2017.

He was acquitted on one count but later convicted on the three others.
