A probable cause affidavit released Monday in the molestation case involving a man infected with HIV and a 7-year-old boy revealed graphic, horrifying details of the case.Indianapolis police said Carl Delong, 33, a friend of the victim's family, was left alone with the boy, 6News' Chance Walser reported.The boy described what happened to him, telling investigators that Delong "would help him shower by washing his body and hair."The boy said Delong also held him down on a bed and molested him. After several months, the boy eventually told his mother."Carl told him daddy would go to jail, and he could get an infection and die," the probable cause affidavit said.Sandy Runkle-DeLorme, director of programs for the nonprofit group Prevent Child Abuse Indiana, said the group is focused on educating parents about recognizing when there might be a problem."There may be behavioral changes where the behaviors may become more sexualized. They may withdraw," she said. "Most of the time, when an incident of sexual abuse occurs, it's a one-on-one situation."The signs were recognized by the boy's mother, police said. She told investigators that her son was suddenly acting out at school and on the bus.Runkle-DeLorme said abuse cases happen too frequently and that one in four girls and one in six boys are sexually abused before they reach age 18, and 90 percent of those abused know their attacker."This can be prevented. Parents just need to really explore and become educated and be willing to ask questions if they don't know something," she said.The boy has been tested for HIV. So far, the tests have come back negative.Delong faces six counts of child molestation and an additional charge of failure to warn the boy that he is HIV positive. He has denied the allegations, though he refused to take a polygraph test, police said.
