Two of the three suspects charged over a killing at a McDonald's parking lot in Edmonton are originally from Newfoundland and Labrador.

Trevor Norman John Legge, 30, and Edward O'Halligan, 27, are each charged with second-degree murder in the March 2012 stabbing death of Billy Canh Ho, 25.

Legge, who now lives in Whitecourt, and Edmonton resident O'Halligan are also both charged with robbery and arson.

Kristen Dawn Farrar, 32, also of Whitecourt, is charged with being an accessory after the fact to murder and arson. Edmonton media have reported that Legge and Farrar had been in a relationship.

Legge, who formerly lived in the central Newfoundland town of Badger, was the subject of an RCMP manhunt in Alberta last August after he allegedly tried to run down officers who were trying to arrest him on unrelated charges.  

After three weeks on the run, he was apprehended west of Edmonton.

He is still facing a raft of charges in that case, including resisting arrest, possession of prohibited weapons, dangerous driving, flight from police, and drug possession.

Police believe the March 2012 stabbing was drug-related, and that Ho had gone to the McDonald's parking lot around 2:30 a.m. for a transaction involving crack cocaine.

Court dates have not yet been set.
