The murder trial is set to being Monday for a man accused in the grisly death of an Armstrong, B.C., teen on Halloween night.
Taylor Van Diest, 17, was found badly beaten on Oct. 31, 2011, while still dressed in her zombie costume. She was left unconscious near a set of train tracks, and died later in hospital.
Matthew Stephen Foerster, 26, is charged with first-degree murder.
He is also charged with sexual assault and unlawful confinement in connection with an attack on a female employee at a Kelowna escort agency.
That case had been unsolved since April 12, 2005, but in Nov. 2011 police said they had matched DNA from the scene of the attack on Van Diest to DNA they had on file from the earlier case.
Police arrested Foerster in April 2012 in the ski resort town of Collingwood, Ont., just north of Toronto, where they say he'd assumed a different identity.
His father, Stephen Roy Foerster, is charged with obstruction of justice and accessory after the fact in the death of Van Diest.
