Charles Miller, a 44-year-old Caucasian man, was found dead in his Staten Island home on April 21, 2016. Investigators determined he had suffered multiple stab wounds and ruled the death a homicide, prompting a full-scale criminal investigation.

Detectives focused on an acquaintance who had been involved in a heated argument with Miller shortly before the killing. Witnesses placed that person near Miller’s home on the night of April 21, and evidence and testimony were presented to a grand jury or at trial. The acquaintance was arrested and charged with second-degree murder and related offenses; a jury ultimately convicted the defendant and imposed a lengthy prison sentence for Miller’s killing.

Anyone who knew Charles Miller, his acquaintances, or who saw activity near his home on April 21, 2016, is asked to share information that could shed more light on the case.
