CPD Detective Reynaldo Guevara’s investigation led to the wrongful murder conviction of Tyrece Williams being overturned, making him the 50th person to be exonerated.

CHICAGO (WLS) — A judge Tuesday overturned the conviction of a man who spent 20 years behind bars for a deadly 1990 shooting.

In a case that former Chicago police Detective Reynaldo Guevara had investigated, Tyrece Williams became the 50th individual to have a murder conviction overturned.

Now, Williams is talking about his long fight to clear his name.

A judge, noting the absence of any physical evidence linking Williams to the murder for which he was found guilty 35 years ago, overturned the wrongful conviction on Tuesday.

Applause and happy tears filled the lobby of the Leighton Criminal Courthouse, where Williams and his family heard the news they waited decades for.

Williams said Guevara framed him for a murder in 1990.

“When you’ve been accused of something you didn’t do and you’ve been locked away for so long, to get your name back, that’s the only thing. I got my name back,” expressed Williams.

In making her decision, a judge said Guevara engaged in a pattern of abuse.

The city of Chicago has paid more than $100 million to defend, investigate and settle misconduct claims involving Guevara.

“It’s important to emphasize that this is the 50th Guevara case where a homicide conviction has been overturned because of his misconduct. That’s astounding,” said Lyla Wasz-Piper, with the Exoneration Project.

Williams, now 57, was released from jail nearly 15 years ago, after serving the whole sentence.

He said his wife and children, one of whom is a Chicago police officer, kept him grounded while in prison.

“I raised my kids from the penitentiary. And now to get out and my kids are grown, 40 years old, they’re still my kids,” Williams said.

The state attorney’s office asked for more time to decide whether to appeal the judge’s ruling. The next court date is later this month.
