Police say at least 100 people died in several countries after Kenneth Law, a 58-year-old former Canadian cook, sold them "suicide kits" on the internet. Law is accused of sending more than 1,200 packages to some 40 countries. Two parents whose children used these kits share their stories. "Literally, he had people online who were encouraging him to take his own life", says David Parfett, whose son Tom took his own life at the age of 22. IMAGES AND SOUNDBITES ARRANGED IN SEQUENCES
