Authorities say the shooter approached the American Fish Company, a waterfront restaurant and bar, via boat and opened fire on the crowd.

They later arrested a man who's been identified as Nigel Max Edge at a public boat ramp in nearby Oak Island.

Edge allegedly told authorities he was a combat veteran injured in the line of duty and had PTSD.

Brunswick County District Attorney John David said the mass shooting has rocked the community.

David also said that his office may seek the death penalty against Edge, who is due to appear in court tomorrow.
