Auchincloss, 62, of Ashland, Ore., whose computers were seized last year in a police investigation of child porn allegations, developed a fixation on his half-nephew, the young John Kennedy Jr., in the late 1960s, Tuesday's New York Post quoted unnamed sources as saying.
The sources said Auchincloss raised the suspicions of the boy's mother, his late half-sister Jacqueline Kennedy Onassis, when he repeatedly asked the 7-year-old to pose for pictures. The Post said that by the 1980s, Auchincloss's fixation on JFK Jr. was such that Onassis banned him from the family.
