An Oklahoma City man is charged with lewd acts to a child one month to the day he was charged with multiple counts of rape.
The investigation started with a note one of the victims wrote to a friend about the abuse she says she endured at the hands of Robert Dunn, Jr. The note was turned over to a school principal who contacted authorities.
Court documents say, "In the note the victim writes she was raped". The girl who was "11-years-old, turning 12" claimed the sexual assaults happened between April and June inside the home and "in the shed/barn on their property".
Investigators say a forensic interview was performed on the girl who detailed several instances of rape.
“After going through and interviewing everyone that may possibly had information in the home. Then they discovered there were actually more allegations with the other juvenile sister,” said Cleveland County District Attorney Greg Mashburn.
A new charge filed Thursday, alleges Dunn exposed himself to the girl's older sister.
During Dunn's November arrest he confessed to detectives admitting, "he knew it was wrong but after the first incident he felt she was, 'holding it over his head'". In that interview court documents say Dunn admitted he knew the age of the victim when the incidents occurred.
“Anytime you have multiple victims in case you do wonder if this is a predator type of person that's going to keep on going if they had not been stopped at this point in time,” said Mashburn.
The district attorney says this is the first time Dunn has been investigated for crimes against children.
He remains in the Cleveland County Jail.
