could a boy sue NJ for getting sexually abused at the age of 18 when he was abused at the age of 9 yrs old.

he was tooken away from his parents at the age of 3 yrs old . He lived in NJ for 7 years under the control of NJ . later NJ dyfs placed the boy in a private church where collected the money from the states . he got sexually abused at the age of 9 by the other boys who lived there . they gave the boy 5 pills in a day . they had no idea that they were turning that boy into something he never was when he wasnt controlled by NJ . the people who worked there didnt care the kids who barely ate . yet they would shove and kick the other boys who lived there , shoving pills in their throat . the boy cried each night hoping that his parents would come and save him, until one day that dream came true . the parents then took him out and NJ DYFS was on his parents back for at least 2 yrs which it is only supposed to be 6 months . the boy that was taken by his parents is now 18 years old in high school , passed all of his classes ,and now is taking ap classes.he is now asking this question.thank you
