Yahir Viveros-Alarcon, 27, died early on Sunday, June 8, 2025, after he was stabbed on the Northwest Side and stumbled, wounded, into a liquor store on West Fullerton Avenue in the Belmont Cragin community area the night before. Area Five detectives of the Chicago Police Department investigated, and the Chicago Sun-Times homicide tracker records his death as a stabbing at 5600 W. Fullerton Ave.
According to police, Viveros-Alarcon walked into RJ Food and Liquor, 5640 W. Fullerton Ave., at about 8:45 p.m. on Saturday, June 7, and a witness discovered that he had been hurt. He had four puncture wounds. The Chicago Fire Department treated him and took him to Loyola University Medical Center in Maywood, where he was pronounced dead at 1:25 a.m. Sunday, according to the Cook County medical examiner's office. An autopsy the next day found he died of multiple stab wounds and ruled his death a homicide.
The most basic facts of the attack remain unknown.
Police said neither Viveros-Alarcon nor the witnesses were able to provide details of what had happened, so it is not known where he was stabbed, by whom or why. No suspect description, vehicle or motive was released, and police said no one was in custody. No reward tied to the case could be found.
Little about his life has been made public. A legal services page that tracks Chicago homicides marked his death with the words "Young man killed," and a Belmont Cragin community group shared the news of his death with neighbors. No obituary, memorial page or family fundraiser could be found for this account. His double surname, Viveros-Alarcon, follows the Spanish-language custom of carrying both the father's and the mother's family names.
West Fullerton Avenue is a busy commercial street through Belmont Cragin, a largely Latino neighborhood of bungalows and small businesses on the Northwest Side. On a Saturday night in June, the stretch near Central Avenue would have been busy with shoppers, drivers and people outside. Because Viveros-Alarcon was able to walk into the store, he was likely stabbed somewhere nearby, perhaps on a side street or in an alley, and someone may have seen him walking, bleeding, toward Fullerton.
His death came in a year when Chicago's killings fell sharply. The city recorded about 590 homicides in 2024 and 416 in 2025, the fewest in about 60 years. Chicago police reported clearing 56 percent of homicides in 2024, though that figure counts cases closed without charges.
Security cameras on Fullerton Avenue businesses, and doorbell cameras on nearby homes, may have captured his path that evening. Residents who saw anything unusual on the night of June 7 may not realize that what they saw is connected to a homicide.
No arrest, criminal charge or court case connected to the death of Yahir Viveros-Alarcon could be found in news archives or public records. More than a year later, there is no public sign that anyone has been held responsible. Anyone who saw Yahir Viveros-Alarcon on the evening of June 7, 2025, or who saw a fight or heard shouting near West Fullerton Avenue and Central Avenue that night, may be able to help. Even a small detail, such as a name overheard, a car seen leaving the area or a conversation remembered, can help detectives move a case forward.
