This is a weird case, arson is a uncommon yet effective way of doing a mass murder there has been some cases around the world like with
John Leonard Orr in America,
Mo Huanjing in china and
Tore Hedin in Sweden but oddly it's a very common thing in Britain with people like
John Thompson, who killed 37 and injured 23 when he set fire to three illegal night clubs after an argument with bartender,
Carl Mills who set fire to a his girlfriend's home in Cwmbran killing three people,
Mark Goldstraw an obsessive loner who while on parole for the manslaughter of Deborah Wheatley Goldstraw killed his girlfriend Samantha Carter by setting fire to her home killing her bother, Marcus, sister, Patricia and her stepfather Roderick Hine in the process,
Peter Tredget, a serial killer who killed 26 people in 11 arson attacks in the late 1970s
I've actually been to Denmark place it's a lot different now as you can imagine I remember when was there I saw the name of the street and it hit me that was the place where the massacre happened it was weird to contrast the bright colourful art displays and upbeat atmosphere with what happened all those years ago.
