A Waukegan man wanted for shooting and killing a 63-year-old grandmother, who tried breaking up an altercation at a party, turned himself in to police on Sunday.

Damar D. McDonald, 32, of Waukegan, was wanted on one count of first-degree murder for the death of Annie Faye Nunnally, 63, of North Chicago.

McDonald came to the Waukegan Police Department Sunday morning and surrendered, according to Waukegan Police Commander Joe Florip.

The homicide occurred around 8 p.m. August 22 in the 600 block of McAlister Avenue in Waukegan. Officers and paramedics responded for 911 calls of a person shot.

Officers found Nunnally lying in the street with a gunshot wound.

Investigators believe that the woman was attending a party at a residence when a verbal altercation broke out between two men, Florip said.

Nunnally attempted to mediate the fight and at least one round was fired, striking the woman.
