A Saint Joseph County man could be sentenced to more than 300 years in prison if he’s convicted on all the charges against him in connection to the sex crimes against children the prosecutor’s office says he’s committed.

Charles Dean Sells, Jr. is charged with 13 counts of child molestation and other sex crimes committed against his victims during a six year span that began in 2011.

According to court documents, some of Sells Jr’s victims are relatives. A not guilty plea was entered by the judge during a hearing on Wednesday.

Sells Jr. is due back in court on September 11.
