Detective Superintendent Kenny Dewar said a murder inquiry has been launched.
He said: "A young man has lost his life and one family is beginning this new year in extremely sad circumstances.
"I am appealing to local residents who may have seen or heard anything in connection with this incident, in particular, the elderly man and woman, who were out walking their dog.
"They may have seen something or have information which could assist our investigation and I am asking them to please get in touch with us."
