»PREVIOUS COVERAGE: Maryland police identify victim in fatal stabbing over Popeyes sandwich
The suspect had been on the run for nearly 10 days. During the pursuit, police turned to social media for help finding McClain.
Police Chief Hank Stawinski said tips from the community and “good detective work” led them to the suspect.
Stawinski said Davis entered the restaurant Nov. 4 and began cutting in a line reserved for the popular menu item. After reaching the front of the line, McClain confronted Davis, sparking the argument between the two, Stawinski said.
As the dispute escalated, both men got out of line and decided to settle the matter in the parking lot.
There, Davis was mortally wounded, investigators said. He was rushed to a local hospital, where he was pronounced dead.
Police said McClain and the victim didn't know each other.
At the time of the fight, the restaurant was filled with at least three dozen people, including children, police said.
A knife was recovered from the scene.
Police said McClain fled in a car with an unidentified woman.
Now in custody, McClain is expected to appear in Prince George’s County District Court Friday for a bail review hearing, according to the Prince George’s County State’s Attorney’s Office.
