CHICAGO — A woman who spent nearly three decades in prison for a murder she did not commit has filed a federal lawsuit against the Chicago Police Department and several individual officers, including a disgraced former detective accused of framing dozens of innocent people.

The 13-count civil complaint filed Monday in the U.S. District Court for the Northern District of Illinois on behalf of Marilyn Mulero, 52, alleges that detectives Reynaldo Guevara and Ernest Halvorsen and other officers engaged in a “number of unconstitutional and egregious acts” and coerced a false confession from Mulero.

She is one of at least 38 people exonerated after being convicted on murder charges due to the misconduct of the officers, according to the complaint. Collectively, the innocent men and women have served more than 800 years behind bars, the complaint says.

“I stand here today because, unlike myself, there’s many other innocent people incarcerated,” Mulero said at a press conference Tuesday, adding, “There are many women that are innocent. And these women are not spoken of.”

The Chicago Police Department said it does not comment on ongoing litigation.

What happened to Marilyn Mulero?

In May 1992, Mulero was 21 years old with two young children. She was in a park on Chicago’s West Side when another woman shot and killed two people. Mulero “did not participate in the shootings or have any knowledge they were going to occur,” her attorneys said.

Yet Mulero was “subjected to brutal and unconstitutional interrogation tactics” to force a confession, including being told she would receive a lethal injection if she did not confess, her attorneys said.

A corrupt Chicago cop destroyed lives.Now victims want justice.

According to the complaint, the officers did not provide Mulero with access to a lawyer, used psychological torture, manipulated and coerced purported witnesses into providing false statements, promised leniency to jailhouse informants in exchange for false testimony and manipulated lineups and identifications.
