Jesse Friedman, the Great Neck, N.Y., teenager whose role in a sexual abuse case a quarter-century ago was portrayed in the Oscar-nominated documentary “Capturing the Friedmans” and came to symbolize an era of sensational, often-suspect accusations of child molesting, was properly convicted and should not have his status as a sexual predator overturned, according to a three-year review that was released on Monday.

In a 155-page report written with very little ambiguity, the Nassau County district attorney, Kathleen M. Rice, concluded that none of four issues raised in 2010 in a strongly worded ruling by the United States Court of Appeals for the Second Circuit were substantiated by the evidence.

Instead, it concluded, “By any impartial analysis, the reinvestigation process prompted by Jesse Friedman, his advocates and the Second Circuit, has only increased confidence in the integrity of Jesse Friedman’s guilty plea and adjudication as a sex offender.”

The review concludes another chapter in a case that came to national attention after the 2003 release of the film, which portrayed both the breakup of a deeply troubled family and what was characterized as a flawed, biased police investigation and judicial process. The case led to guilty pleas in 1988 by Jesse Friedman, then 18, and his father, Arnold Friedman, who ran a popular computer class at his house on Piccadilly Road in the affluent Long Island community of Great Neck.
