Manuel Mejia Perez, 13, male, Hispanic/Latino, spent the first Monday of June walking a familiar stretch of Joliet’s southeast side before turning into the narrow alley off the 300 block of Des Plaines Street. It was June 2, 2025, late afternoon, when gunfire broke the quiet. Officers arriving around 4:40 p.m. found the seventh grader on the ground with fatal wounds; he was pronounced dead a short time later, and the Will County Coroner ruled the case a homicide.
The killing would become Joliet’s first homicide of the year, a distinction his family would have traded for obscurity in an instant.
News of the shooting moved quickly through the neighborhood and then the city, carried by the stark details of a child lost in an alley and the raw grief of a mother who told reporters her son was innocent and begged for justice. A GoFundMe set up by relatives shared his name—Manuel Mejia Perez—and asked strangers for help with funeral costs, the kind of public plea that turns a private loss into a community vigil. Flowers and messages began to gather while detectives canvassed, piecing together a timeline from shell casings, camera angles, and the murmurs of those who knew both boys.
Within forty-eight hours, investigators said they had solved the alley murder. A 15-year-old boy—also from Joliet—was arrested and charged with three counts of first-degree murder and one count of aggravated unlawful possession of a weapon. Because of his age, authorities did not release his name, but they laid out the broad strokes: the victim and suspect knew each other; this was not random; and the confrontation in the alley ended with the younger boy shot and left where he fell. Police Chief Bill Evans offered condolences to the family as the juvenile was placed into custody.
As the charges were announced, more pieces emerged from the investigation. A police summary indicated that detectives believed the suspect shot Manuel Mejia Perez twice during a dispute, and that earlier in May the same teen had been detained on an unrelated incident before being questioned in the killing. The suggestion of an ongoing personal conflict between the boys complicated the simple narratives people reach for when a child is taken; it did not soften the fact that one was gone and the other was now facing the gravest accusations the law can bring against someone his age.
Days later, the rhythm of a city resumed while the family planned a funeral. An obituary confirmed what the headlines had already made impossible to forget: Manuel Mejia Perez was thirteen, born in 2011, and his life ended on June 2, 2025, in Joliet, Illinois. The investigation had produced a suspect and charges, but the loss remained, carried by a mother’s call for justice and a community that had watched a summer begin with sirens in an alley.
