A former Memphis police officer was found guilty of multiple rape and incest charges Thursday evening.

Cornelius Monger, 36, was found guilty by a jury of statutory rape by an authority figure, sexual battery by an authority figure, and incest. He will be sentenced on Jan. 15 by criminal court Judge Glenn Wright, Shelby County District Attorney Amy Weirich said in a press release.

The victim and witnesses testified during the trial that the abuse began when the victim was 15 and continued for years.

Monger's father, Henry Monger, is currently serving a 15-year sentence for raping the same victim and her siblings. Henry Monger, 64, pleaded guilty in April to two counts of rape of a child and one other rape charge. One of the victims said he began abusing her when she was 10-years-old, according to investigators.

Henry's wife Barbara is set for trial in February. She has been charged with allegedly telling the victims not to cooperate with officers investigating Henry's actions.

Cornelius Monger served at the Old Allen Station from 2006 to 2013, Weirich said. He was fired due to the allegations.
