Jacqueline Montanez: Conviction, Clemency, and Life After Release

Jacqueline Montanez is a Chicago woman who, at age 15, shot and killed two Latin Kings members in Humboldt Park in May 1992, was convicted of first-degree murder and given a mandatory sentence of life without parole, and was released in 2022 after 31 years in prison following a resentencing made possible by U.S. Supreme Court rulings against mandatory life-without-parole sentences for juveniles. She was the first woman in Illinois sentenced to die in prison for a crime committed as a child.¹ Years later, she came forward to say she alone carried out the killings, a statement that helped exonerate two co-defendants convicted on evidence built by disgraced Chicago detective Reynaldo Guevara.

The Humboldt Park Killings

On May 12, 1992, Hector Reyes, 21, and Jimmy Cruz, 22, both members of the Latin Kings, were shot to death in Humboldt Park on Chicago’s West Side. Prosecutors said Montanez and two other teenage members of the rival Maniac Latin Disciples lured the men to the park to avenge the earlier killing of a fellow gang member known as “Mudo.” Montanez flirted with Reyes, then shot him in the back of the head inside a public washroom. She handed a .25-caliber revolver to another girl, who shot Cruz in the back of the head as he walked outside.²

She was arrested along with two co-defendants: Marilyn Mulero, then 21, and Madeline Mendoza, then 16.³ The investigating detectives were Reynaldo Guevara and Ernest Halvorsen, whose conduct across dozens of Chicago cases would later be exposed as corrupt.

Her Life Before the Crime

Montanez grew up on Chicago’s West Side in a household marked by domestic violence and drug use. She was physically and sexually abused by her stepfather, whom she described as a “gang lord.”⁴ She started drinking and using drugs at nine, was intermittently placed in social services custody starting at 12, and ran away from a foster home.⁵ Her stepfather initiated her into his gang; she later joined a rival gang trying to escape him. She dropped out of school in the seventh grade.

Trial and Mandatory Life Sentence

Under Illinois law at the time, Montanez was automatically transferred to adult criminal court despite being 15. That meant her youth, history of abuse, and mental health issues could not be weighed as mitigating factors at sentencing. She was convicted of first-degree murder in 1993 and received a mandatory life-without-parole sentence. She was transferred to an adult jail on her 17th birthday and moved to adult prison four months later, spending nearly three years in a mental health unit.⁵

Her first conviction was vacated in 1995 because her confession was found to be involuntary. A retrial in 1999 produced a second conviction and the same mandatory life sentence.⁶

Amnesty International took up her case, arguing that sentencing a 15-year-old to die in prison violated the International Covenant on Civil and Political Rights and the Convention on the Rights of the Child.⁷ Montanez filed a clemency petition with the Illinois Prisoner Review Board in January 2012, and the Board held a hearing that April. Governor Pat Quinn left office in January 2015 without acting on it.⁸

How Miller v. Alabama Got Her Out

The legal footing under her sentence collapsed in June 2012, when the U.S. Supreme Court ruled in Miller v. Alabama that mandatory life-without-parole sentences for juvenile offenders violate the Eighth Amendment. The Illinois Supreme Court later held the ruling applied retroactively, making people like Montanez eligible for new sentencing hearings.⁹

On October 14, 2016, Cook County Judge Alfredo Maldonado resentenced Montanez to 63 years. He called the 1992 killings a “senseless tragedy” but said she “didn’t deserve life in prison” and was “not one of those rarest of juveniles” for whom that sentence would be appropriate.¹⁰ He also said she was “clearly not the same person she was when she murdered the men.”⁹ Under Illinois truth-in-sentencing rules, the 63-year term was to be served at 50 percent. With credit for time already served, she became eligible for release. Northwestern University’s Bluhm Legal Clinic assisted in the resentencing.⁴

In prison, Montanez had earned a high school equivalency diploma, become a certified trainer of service dogs for people with disabilities, been published as a poet, and mentored other incarcerated women.⁸ The death of her mother in 2008 marked a turning point; she moved away from gang activity and fighting and pursued education and vocational training.⁴

The 2017 Confession That Cleared Her Co-Defendants

In January 2017, Montanez came forward with a written statement, and repeated verbal admissions, saying she alone planned and carried out both killings and that Marilyn Mulero and Madeline Mendoza had nothing to do with the murders.¹¹¹²

Mulero had been coerced into a confession by detectives Guevara and Halvorsen, according to her later lawsuit, and pleaded guilty in 1993 on the advice of an attorney with no death penalty experience. A jury recommended death, and she was sentenced to die in November 1993.⁶¹³ She spent five years on death row before the Illinois Supreme Court vacated the death sentence in 1997, and a 1998 resentencing gave her life without parole instead.³ After Montanez’s 2017 statement and years of work by the California Innocence Project and the Exoneration Project, Governor J.B. Pritzker commuted Mulero’s sentence in 2020, and she was released after 28 years. The Cook County State’s Attorney vacated her conviction in August 2022 and dismissed the case.

Mendoza had pleaded guilty in September 1993 and served 17 years of a 35-year sentence, leaving prison in 2009. On January 3, 2023, Judge Maldonado vacated her convictions for two counts of first-degree murder and one count of conspiracy. Prosecutors did not oppose the motion and dropped all charges. Her petition alleged that Guevara and Halvorsen fabricated evidence to implicate her, including soliciting false information from a jailhouse informant, and that she had no prior knowledge of the plan and did not take part in the shootings.¹⁴

Guevara’s misconduct has been linked to the wrongful imprisonment of at least 41 people, built on coerced confessions, fabricated evidence, and manipulated witnesses in the 1980s and 1990s. He was never disciplined during his 29-year career, is now retired, and has repeatedly invoked the Fifth Amendment in civil proceedings.¹⁵

Life After Release

Montanez was released in 2022 after serving 31 years in maximum-security facilities in Illinois and Florida.¹⁶ She had entered the prison system at 17 and spent her entire adult life incarcerated. During those years she experienced sexual assault, a pregnancy that ended in the loss of the baby, and severe depression, with what she has described as inadequate mental health support.⁴

Since her release she has worked as a prison reform advocate and motivational speaker, is affiliated with the youth advocacy group “Queens for Queens,” and takes children on motivational trips. She volunteers in prisons to mentor incarcerated women and in Chicago to feed the homeless, and she has been working to launch a nonprofit called “Future for Tomorrow’s Youth” that would offer free dog training and grooming instruction as an alternative to gangs and drugs.¹⁶⁴

Reentry has been hard. She has reported being fired from three jobs after employers ran background checks. She continues to manage post-traumatic stress from decades inside, including trouble sleeping, discomfort using metal silverware, and difficulty adjusting to life outside the structured rhythm of a prison day room. Reconnecting with family has also been a struggle; she has said that despite her efforts, “family just moves on.”⁴
