Ricoh McClain, 30, who had been at large since the attack on Nov. 4 in Oxon Hill, was located and arrested Wednesday, according to the Prince George’s County Police Department.
No further details on McClain’s arrest were immediately available.
McClain reportedly stabbed Kevin Tyrell Davis after Davis allegedly cut the line at the Popeyes restaurant, where sales of a popular new chicken sandwich have been linked to a series of violent incidents reported at various Popeyes locations in recent weeks.
When officers arrived at the Oxon Hill restaurant they found Davis suffering from stab wounds, FOX 5 of Washington reported. He was transported to a hospital but eventually died from his wounds.
Speaking to reporters later, Prince George's County Police Chief Hank Stawinski called the stabbing a "pointless crime" and said there was no indication that McClain and Davis knew each other.
Authorities identified McClain as the suspect Tuesday, saying he was being charged with first-degree murder, second-degree murder, first-degree assault, second-degree assault and reckless endangerment and was considered armed and dangerous.
Popeyes resumed selling its chicken sandwich Sunday after an interruption. The menu item was initially released Aug. 12, but popular demand caused the chain’s supply to sell out by the end of that month.
In a statement to Fox News last week, a Popeyes spokesperson said, “Our thoughts are with the victim’s family and friends and we are fully cooperating with local authorities.”
