A Crime & Investigation Network documentary explaining how John Martin (born John Martin Scripps, 9 December 1959 – 19 April 1996) was an English spree killer who murdered three tourists—Gerard Lowe in Singapore, and Sheila and Darin Damude in Thailand—with another three unconfirmed victims. He posed as a tourist himself when committing the murders, for which British tabloids nicknamed him “the tourist from Hell”. He cut up all his victims’ bodies, using butchery skills he acquired in prison, before disposing of them.
