PHILADELPHIA (AP) — A man who served nearly three decades in prison for a triple killing in Philadelphia in what prosecutors called a “perfect storm” of injustice was freed after a judge threw out his conviction.

“Theophalis Wilson, you are free to go,” Judge Tracy Brandeis-Roman said Tuesday as extended family and friends who packed the courtroom cried and hugged each other.

“This is a great day,” said Wilson, 48, who served 28 years in prison. “Now we’ve got to go back and get the other guys. There’s a lot of innocent people in jail.”

Wilson was exonerated a month after his co-defendant, Christopher Williams, was cleared of the three 1989 killings. Wilson was a teenager when he was accused of participating in the slayings of Otis Reynolds and brothers Kevin and Gavin Anderson in north Philadelphia.

The Philadelphia district attorney’s office called the case a “perfect storm” of injustice, writing in a court filing that the case was marred by serious misconduct by the prosecution, an ineffective defense and a witness who supplied false testimony.
