Tuesday, a Cook County judge vacated the murder conviction of Marilyn Mulero and dismissed all charges against her.

Mulero, an alleged victim of the notorious former Chicago Detective Reynaldo Guevara, spent nearly three decades in prison for a 1992 murder.

Mulero is the first and only female victim of Guevara to be exonerated among over 30 Guevara-related homicide convictions overturned to date.

This morning her case was one of eight pending murder convictions heard at the Cook County Courthouse at the request of the Cook County State’s Attorney.

Mulero was convicted of a 1992 murder based on evidence allegedly fabricated by Guevara.

Officials say after a marathon 20-hour interrogation session she signed a statement “confessing” responsibility for a murder.

She spent the next 28 years, including five on death row, fighting for her innocence.

In April 2020 Gov. JB Pritzker commuted Mulero’s life sentence and she was released.
