the older of Joanne's sons, had disciplinary problems. In an attempt to address those problems, Joanne went to Lackawanna County Children and Youth Services (CYS). One of the measures attempted was to send David to live with an aunt, Joanne's sister, in the Allentown area. Once there, David told the aunt that there might be problems with Blasi being at home alone with Michael. The aunt called Joanne and advised her to seek counseling for Michael, which Joanne did.
After initial reticence, Michael told the counselor, Robert Frein, of incidents which occurred at home while his mother was working. These consisted of Blasi watching pornographic movies and masturbating, then having Michael masturbate. During subsequent interviews with Frein and either police or CYS personnel, Michael related that the incidents alsoinvolved Blasi touching Michael (including both masturbation and performing oral sex), and vice versa. Eventually, Michael told of two instances in which Blasi anally penetrated Michael.
Michael was unable to specify the dates on which the incidents, numbering either four or five altogether, took place. However, they began in either late February or early March, 1992, and ended in late March or April of the same year. Michael estimated the dates based on their relation to his birthday.
