On July 7, 2022, North Bergen police responded to a home on Dane Court and found a 2-year-old girl unresponsive on a bedroom floor. The child was transported to Hackensack University Medical Center in critical condition and died on July 23, 2022. The cause of death was determined to be complications following blunt force injuries, with the manner of death ruled undetermined by the New Jersey Chief State Medical Examiner. The child's parents, Tracy Ruiz and Luis Larios, were charged nearly two years later — Ruiz with second-degree aggravated assault and two counts of endangering the welfare of a child, and Larios with endangering the welfare of a child — though neither was charged with homicide. Three other children lived in the apartment, which was described as being in unsanitary condition.

Notable Details
Several notable details emerge from the source text. The news article notes that charges were not brought until nearly two years after the child's death, via a grand jury indictment signed on February 21, 2024. Despite the cause of death being "Complications following Blunt Force Injuries," "neither person has been charged with homicide." The manner of death was officially ruled "Undetermined" per the medical examiner report. Additionally, the article notes that "Three other children lived in the apartment, which Suarez said was in an unsanitary condition," and "The prosecutor's office did not provide any details on the child's death," suggesting limited transparency. The combination of blunt force injuries as cause of death, an undetermined manner of death, and the absence of homicide charges is an unusual legal and forensic posture that may materially affect a researcher's understanding of the case.
