A third defendant in the case - Dorothy Prawdzik, 44, of Drexel Hill - faces various counts of aiding and abetting Worman.
The mother testified yesterday that, in 2003, she answered an advertisement placed by Jackson offering her babysitting services. (It is The Inquirer's policy not to identify victims of sexual abuse.)
The mother said she went to Jackson's Collingdale home for their first meeting. They talked about hours, cost, and safety.
"I had her walk me through the residence to see if there were certain safety precautions," the mother said. She checked for smoke alarms, gates, sharp objects, and where the animals would be while her children were there. The mother even checked out the refrigerator and oven to see if they were safe.
She asked who lived at the home.
"She [Jackson] told me it was only her and her children," she said. Later, she testified, she went so far as to conduct a criminal background check of Jackson.
A few weeks after she started dropping off her children, she met John Worman, whom Jackson introduced as her "fiance." A few weeks later, the mother learned Worman had moved into the home.
The mother said in an interview yesterday that three months after she began using Jackson's service, she received a call at work. Jackson told her to get her children and their things.
"You can't have them here anymore," she said Jackson told her.
She testified that, about three years later, she received another call while at work. It was her husband, who told her to come home immediately. Delaware County Detective Sgt. John Kelly had come to their home with pictures.
A few months earlier, police had arrested Worman and recovered 11,000 video images and 1.2 million still images of child pornography from his computers. Prosecutors allege that, over a nine-year period, Worman molested at least 12 children, ranging in age from 3 months to 15 years, who were in his care at the time of the offenses.
