An investigation followed to identify a perpetrator and motive. The case remained unsolved for a significant period before a suspect was later arrested and charged in connection with the killing. That suspect is in custody awaiting trial, which has been delayed several times, including delays attributed to the COVID-19 pandemic.

Anyone who knew Marvin, saw activity in the 400 block of 155th Street on October 27, 2018, or has information relevant to the case is asked to come forward.
