The Canadian man alleged to have sold poison to more than 40 countries including New Zealand has had his charges upgraded to first-degree murder.
Kenneth Law has received 28 charges in total, half of those are for murder and the rest for aiding suicide.
CBC News' Senior Reporter Thomas Daigle says although more than 1200 packages are believed to have made their way around the world, it seems that number may be higher now.
Daigle spoke to Ingrid Hipkiss.
