On September 13, 2012, a 41-year-old Black male named Mario L. Dunnville was found dead in Indianapolis, Indiana, becoming the victim of a homicide that remains unresolved. The incident occurred at a specific location on the east side of the city, identified in police records as 7020 East 21st Street. This address places the crime scene in a residential area near the intersection of 21st Street and Shadeland Avenue. Authorities responded to the scene where they discovered Dunnville's body, marking the beginning of a murder investigation by the Indianapolis Metropolitan Police Department.
Despite the immediate launch of an investigation, details surrounding the circumstances of the killing were scarce from the outset. Police had no immediate suspects in custody, and initial reports provided little information regarding a motive or specific witnesses to the crime. The case was eventually cataloged in databases dedicated to cold cases and unsolved homicides, including a national initiative partnering with major news outlets to track murder clearance rates in large cities. As of the last available updates, no arrests have been made, and the suspect information remains listed as unknown.
Following the tragedy, family and friends gathered to mourn Dunnville. His obituary, published in the local newspaper, announced that funeral services were held on September 20, 2012, at Lavenia and Summers Home for Funerals. He was subsequently laid to rest at Sutherland Park Cemetery. Over a decade later, his death stands as one of the many unsolved homicides from that year in Indianapolis, with the case file still open but inactive pending new leads.
