A man in Canada charged with aiding suicides by distributing lethal products online is now facing 14 counts of second-degree murder.
Police in the province of Ontario say the man sent packages to people in as many as 40 countries, and several deaths in New Zealand may be linked to him.
In August, 58-year-old former chef Kenneth Law was charged with 14 counts of counselling or aiding suicide for marketing and distributing products linked to deaths in Ontario, Canada.
Now, he's facing more serious charges.
"Evidence has come in that supports the charge of second-degree murder. I can't speak to that evidence at this time, to preserve the investigation," York Regional Police Inspector Simon James said.
Law is accused of sending about 160 lethal packages to people in 40 countries.
"We are aware of other police investigations in other jurisdictions outside of the province of Ontario and we are aware of other investigations in other countries," Insp James said.
The Ministry of Justice told Newshub the Coroner is investigating several deaths which may be linked to Law.
An international law expert said that if there is evidence of a link, the Canadian man could be forced to answer to the New Zealand legal system.
"The Coroner would get the prosecutors involved. They'd have to investigate whether they think there's been an offence in New Zealand," AUT law professor Kris Gledhill said.
"If the authorities in New Zealand think there has been, they could make a request to the Canadian authorities to have him extradited from Canada to New Zealand to stand trial."
However, Gledhill suggests that's unlikely - because the accused may end up serving a life sentence in Canada.
"Then there might be various other governments who've already made extradition requests, and so the Canadian authorities would have to decide what the order of priority would be."
Law is in custody and is due to appear in an Ontario court on December 19.
