Portland Press Herald Photo   When 16-year-old Jessica Briggs was found dead under the Maine State Pier in Portland in May 1989 — stabbed, beaten and eviscerated — police quickly narrowed their focus to her fellow street kids. They arrested her sometime boyfriend Tony Sanborn in 1990, he was convicted of her murder in 1992 and an appeal failed in 1994. In April, after 27 years behind bars, Sanborn was let out on bail after attorneys spent more than a year combing through police and prosecution files that show a trail of lies and constitutional violations. The star witness? 13 at the time of the murder? Turns out she was legally blind and couldn’t see what she’d claimed she’d seen, something the prosecution didn’t share with the defense. Another important witness? Police had threatened to pursue the adult man’s sexual assaults on underage girls unless he testified that Sanborn told him he’d killed Briggs. The defense didn’t know about that, either. And that’s just the beginning. Sanborn’s release was a first for Maine, but what lead to it will blow your mind. Join us for Episode 22!
