Railyana Vasquez was a one-year-old toddler killed in Chicago on November 8, 2016. The Cook County Medical Examiner ruled her death a homicide from multiple injuries consistent with child abuse, including a lacerated liver and severed arteries.

Investigators say Railyana’s mother left her in the care of her mother’s boyfriend, Uriel Vega, while she attended church. Prosecutors allege Vega threw the child across a room, then stomped on her stomach. Vega called 911 when he noticed the child having trouble breathing; she was pronounced dead soon after arrival at the hospital. Vega was arrested and charged with first-degree murder and is being held without bond.
