MacDonald was last seen around 11 p.m. July 7, at an Irving gas station in North Sydney, N.S.

Police said in November that they were treating his disappearance as a homicide.

Earlier this month, police charged 38-year-old Mitchell George McPhee with MacDonald’s manslaughter, as well as robbery and assault.

Police said in a statement late Saturday night that no further details will be released as the investigation continues, and more charges and arrests are pending.
