Cape and Islands District Attorney Michael O'Keefe and Barnstable Police Chief Matthew Sonnabend on Friday identified the victim of Wednesday afternoon's shooting as 33-year-old Darrell Russ, of Hyannis.
The medical examiner determined that Russ died of three gunshot wounds.
No arrests have been announced and authorities have not disclosed a possible motive.
Police responded to a 911 call about a physical altercation. Witnesses reported seeing a shouting match involving four men.
The Cape Cod Times reports that one witness said he saw two of the men involved in the argument speed away in a car.
