Two-year-old Mars Jones died of complications of inflicted blunt-impact head trauma, ruled a homicide by the D.C. OCME. On October 13, 2022, in the unit block of Atlantic Street SW, Dasean Matthews — the 23-year-old romantic partner/friend of Mars's mother — was captured on surveillance video violently swinging the toddler so his feet were above his head, then dragging and striking him in an apartment lobby. After taking Mars on an errand, Matthews called the mother saying the child was not breathing and returned with him unconscious in the car; the mother attempted CPR. Mars was hospitalized and pronounced dead about five days later from his injuries. Matthews was arrested and charged with first-degree murder.

Notable Details
The source PDF notes a data limitation relevant to interpreting this case: "the file included the 'postmortem examination date', but not the exact date of death. As such, some reported dates of death for DC may be slightly off." Additionally, the case is notable for detailed surveillance-footage evidence cited in charging documents, which the WUSA9 article reports captured Matthews "swinging him around with such force that the two-year-old 'was suspended in the air and spun around with his feet above his head'" before the child was hit and later died. The child survived for several days in the hospital before being "pronounced dead five days later due to his injuries."
