J.R. Allen, who was indicted last year along with Dulaney, was arrested in the Middle Fork area of Magoffin County.
Last summer, Sally Vance was a passenger in a vehicle driven by Dulaney when she was shot during an exchange of gunfire between that vehicle and a house in Allen. Now Allen is in custody in connection to that shooting charged in his indictment with murder and a count of possession of a firearm by a convicted felon.
It has still not been exclusively determined how Vance was shot during the exchange, other than prosecutors saying it is believed she was struck by a stray bullet.
Dulaney was arrested in the Banner area shortly after the shooting took place last summer after being questioned by state police officers during a traffic stop.
Allen is currently being held at the Big Sandy Detention Center in Johnson County.
