Police arrested one suspect Tuesday morning and continue searching for another after a 63-year-old woman was fatally shot while trying to break up an altercation in Waukegan.

Achley Cruz-Oquendo, 32, of Waukegan, was arrested early Tuesday morning in Waukegan by police officers on the charge of obstruction of justice.

Damar McDonald, 32, of Waukegan, who is wanted on the charge of first-degree murder, remains on the loose and police continue to search for him.

The Waukegan Police Department and Waukegan Fire Department responded around 8 p.m. Saturday to the 600 block of McAlister Avenue for a report of a person shot call.

Officers found a 63-year-old North Chicago woman, identified as Annie Nunnally, lying in the street with a gunshot wound.

Investigators believe that Nunnally was attending a party at a residence when a verbal altercation broke out between two men, Waukegan Police Commander Joe Florip said.

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

Nunnally then ran into the street where she was found by officers, Florip said. She was transported to an area hospital and pronounced dead.

Florip said that it is believed that McDonald fired the shot or shots that struck the woman.

Florip said that Cruz-Oquendo obstructed the investigation due to “her actions that evening.” She remains held in the Lake County jail on a $250,000 bond.

The Lake County Coroner’s Office conducted an autopsy on the victim on Tuesday and confirmed that Nunnally died as a result of a gunshot wound.

McDonald is considered armed and dangerous, Florip said. His active warrant carries a $3 million bond.

Anyone with information on his location is asked to call the Waukegan Police Department’s Criminal Investigations tip line at 847-360-9001 or 911 if you spot him.
