The American euthanasia advocate Jack Kevorkian passed away on Friday, aged 83. Kevorkian claimed to have helped more than 130 people to die during his career, beginning with the assisted suicide of a woman with Alzheimer’s disease in 1990. He advertised his services as a “death counselor” in a Detroit newspaper. Many of the killings were performed with euthanising drugs administered by his DIY Thanatron (“death machine”), or else by asphyxiation with the use of his patented Mercitron (“mercy machine”). Kevorkian was tried and found guilty of second-degree murder in 1999 and sentenced to 10-25 years in prison. He got out on parole in 2007. He claimed he had a terminal illness, but was fit enough to run for Congress in 2008. “Dr Death” took 2.6 percent of the vote.
