CHICAGO — A 7-year-old girl was fatally stabbed on a South Side Chicago sidewalk on Saturday morning, an attack that has unsettled residents of the Chatham neighborhood and reignited debate over crime and mental health interventions in the city.

Eddimar Hernandez Chacon was walking hand-in-hand with her 17-year-old sister along Cottage Grove Avenue when a 48-year-old woman, identified as Shavon Gayden, allegedly approached and unexpectedly stabbed the younger girl multiple times in the back. The older sister dodged the assault and bystanders quickly intervened, restraining Ms. Gayden. Despite attempts at resuscitation by bystanders and a police officer, Eddimar died at the scene.

Authorities said there is no evidence that the victim was specifically targeted. Prosecutors stated that prior to the stabbing, Ms. Gayden had threatened a store clerk and drew a knife from a themed bag before attacking the children.

Ms. Gayden was hospitalized with a head injury sustained during her apprehension and has been charged with first-degree murder. She had not yet appeared in court as of early this week.

The incident has drawn attention to Ms. Gayden’s extensive history of legal trouble and mental health challenges. Court records reveal that over the past decade she faced multiple accusations of domestic violence, although some cases were dismissed. In 2024, she pleaded guilty to a felony aggravated battery charge for threatening a bus driver with a knife and received two years’ probation. Last year, she pleaded guilty to misdemeanor battery for attacking a police officer and a homeless shelter employee where she had been residing.

Ms. Gayden violated the terms of her probation earlier this year, resulting in a warrant for her arrest. However, she was not detained in connection with probation violations during subsequent court appearances, raising questions about the oversight of her case. Following her arrest at the homeless shelter, a judge ordered her release within two months.

Family members acknowledge Ms. Gayden’s struggles with mental health. Her mother, Christine Gayden, expressed frustration about efforts to secure help for her daughter.

Community members were visibly shaken by the stabbing, which struck a chord in a neighborhood long regarded as a stable, middle-class Black enclave. Local residents described Ms. Gayden’s prior erratic behavior, with some recalling incidents in public settings where she acted aggressively.

Witnesses at the scene included Tiera Whalum, who was parked nearby waiting for an appointment. She described initially misunderstanding the attack, thinking the woman was swatting at the child until she realized what was happening. Ms. Whalum, a nursing student, assisted with first aid and CPR efforts in the moments after the assault.

Mayor Brandon Johnson, who has emphasized crime reduction during his re-election campaign, described the loss of a young life as especially tragic. Meanwhile, former President Donald Trump renewed calls for federal law enforcement intervention in Chicago, citing an ongoing rise in violent crime, though he did not reference this specific incident.

A makeshift memorial of candles, flowers, and toys remained on the street corner where Eddimar was attacked, reflecting the community’s mourning. Some residents stressed the need for expanded mental health resources to prevent future tragedies, pointing to Ms. Gayden’s known difficulties and the gaps in support that preceded the fatal attack.
