Hearing to determine evidence allowed at trial of man accused in bombing death

RED DEER, Alta. - A hearing is underway to decide what evidence to allow at the trial of a man accused of killing a young woman with an exploding package outside her door in central Alberta.

Brian Malley, who is 57, is charged with first-degree murder and two explosives-related counts.

The evidence presented at the voir dire cannot be made public.

Vicky Shachtay (SHAK'-tay) died in November 2011, when a hand-delivered package left on the doorstep of her townhouse in Innisfail blew up.

Shachtay, who was 23, was a single mother and used a wheelchair following a car accident.

The hearing is expected to last two weeks with Malley's trial to go ahead in January
