Prosecutors have 'bizarre' letters Sandusky wrote to victim, source tells NBC Forty prospective jurors were interviewed for the sexual abuse trial of former Penn State Coach Jerry Sandusky. By Michael Isikoff, NBC News BELLEFONTE, Pa. - Prosecutors have obtained multiple incriminating and "bizarre" letters that former Penn State assistant football coach Jerry Sandusky allegedly wrote to one of his accusers in his sexual abuse trial, a source familiar with the evidence tells NBC News. The letters were written to one of the boys Sandusky is accused of sexually abusing, known so far in court documents only as Victim #4, said the source, who spoke on condition of anonymity. Prosecutors plan to start their case next week by reading copies of the letters to support the state's charges that Sandusky repeatedly had improper sexual relations with the boy, the source said. Prosecutors declined to comment on the purported letters, the existence of which was first reported Tuesday evening by ABC News. According to the indictment handed up against Sandusky, the defendant met the boy through his Second Mile charity and slowly won his trust by giving him gifts and other rewards. "Victim 4 became a fixture in the Sandusky household, sleeping overnight and accompanying Sandusky to charity functions and Penn State football games," it said. ...." Usually the persuasion Sandusky employed was accompanied by gifts and opportunities to attend sporting and charity events. He gave Victim 4 dozens of gifts, some purchased and some obtained from various sporting goods vendors such as Nike and Airwalk.
