Clenix Martin was 30 when his body was found in Omaha on May 12, 2008; investigators determined he had been shot to death. His killing came shortly after he testified as a witness against Roy Ellis in the murder of Amber Harris, testimony that helped secure Ellis’s conviction. Because of that timing, many believe Martin’s cooperation with prosecutors may have led to his murder as retaliation.

Despite the apparent motive and the case’s connection to a prior high-profile killing, no arrests have been announced and no suspects have been publicly charged. Authorities have continued to seek tips from the public as the investigation remains unresolved.

If anyone knew Clenix, his movements in May 2008, or has information about who might have targeted him, please come forward.
