Drops of blood help convict jewelry store robber 2 years after crime

NORTH VANCOUVER, B.C. - It reads like a script right out of TV's CSI — a few drops of blood and some patient police work solved a B.C. jewelry store robbery dating back more than two years.

In an overnight heist in May of 2009, two men broke through the glass doors of the Romance Jewelry store in North Vancouver and scooped up more than $91,000 worth of jewels.

A careful examination of the crime scene by police turned up some drops of blood on a shard of glass.

RCMP investigators say a DNA match of the blood led them to 37-year-old Jason Liss of Abbotsford, who was found living in Vancouver.

Because he was considered armed and dangerous, a Vancouver police emergency response team was brought in to arrest him in October.

Last week, Liss pleaded guilty to the robbery and is now serving a two-year prison term and must repay the store an equivalent amount of the jewels taken in the heist.
