What to Watch on Friday: 20/20 has Central Park 5 doc, and it’s the last call for ‘Last Call’


20/20: One Night in Central Park (9 p.m., ABC) - 30 years after the brutal rape and beating of jogger Trisha Meili in New York’s Central Park, ABC News gives us a close look at the shocking case, which triggered a media frenzy and left five young men wrongly imprisoned. The verdicts were later set aside when Matias Reyes confessed to the crime and was convicted. This documentary special features a rare interview with Meili, and an archival interview Reyes from the ABC vault. Also, interviews with police involved in the case, who speak for the first time since a gag order was lifted.
