manslaughter or foul play. Naifeh and Smith point out that the bullet entered van Gogh's abdomen at an oblique angle, not straight as might be expected from a suicide. They claim that van Gogh was acquainted with the boys who may have shot him, one of whom was in the habit of wearing a cowboy suit, and had gone drinking with them. Naifeh said: "So you have a couple of teenagers who have a malfunctioning gun, you have a boy who likes to play cowboy, you have three people probably all of whom had too much to drink." Naifeh concluded that "accidental homicide" was "far more likely". The authors contend that art historian John Rewald visited Auvers in the 1930s, and recorded the version of events that is widely believed. The authors postulate that after he was fatally wounded, van Gogh welcomed death and believed the boys had done him a favour, hence his widely quoted deathbed remark: "Do not accuse anyone... it is I who wanted to kill myself." On 16 October 2011, an episode of the TV news magazine 60 Minutes aired a report exploring the contention of Naifeh and Smith's biography. Some credence has been given to the theory by van Gogh experts, who cite an interview with French businessman René Secrétan recorded in 1956, in which he admitted to tormenting—but not actually shooting—the artist. Nonetheless, this new biographical account has been greeted with some scepticism. Sceptic Joe Nickell also was not convinced and offered alternative explanations. In the July 2013 issue of the Burlington Magazine, two of the research specialists from the Van Gogh Museum in Amsterdam, Louis van Tilborgh and Teio Meedendorp, present a theory that at the time of his death, van Gogh was in a troubled state and in danger of suicide. They also present alternative explanations to the theories presented by Naifeh and Smith. In 2014, at Smith and Naifeh's request, handgun expert Vincent Di Maio reviewed the forensic evidence surrounding Van Gogh's shooting. Di Maio noted that to shoot himself in the left abdomen Van Gogh would have had to have held the gun at a very awkward angle, and that there would have been black powder burns on his hands and tattooing and other marks on the skin around the wound, none of which is noted in the contemporary report. Di Maio gave his conclusion that and to which Nickell
