On 15 March 1986, the body of a 37-year-old murder victim named Alex Kasson was found in a derelict flat in Kensington, London. The investigation did not make much progress because there were no obvious link between a perpetrator and the dead man.
On 6 April that year, the corpse of Anthony Connolly, 24, was found on a railway embankment in Brixton. He had been strangled to death with his own scarf. Because Connolly had been sharing a flat with a man who was HIV positive, there was a long delay between the discovery of the body and the post mortem because the coroner wanted to make sure Connolly was not himself infected with HIV. This created serious tensions between the authorities and the gay community, the latter accusing the former of dragging their heels and not taking the death of a gay man seriously enough.
Trial and imprisonment
Six weeks later, on 18 May, Michele de Marco Lupo was arrested and charged with the murders of Connolly and Burns. Lupo, who ran a flower shop in Chelsea, was originally from Italy and a former soldier. He apparently called himself "The Wolf Man" ("lupo" means "wolf" in Italian) and boasted of having had 4,000 lovers.
On 21 May, Lupo was charged with two other recent killings, those of a young hospital worker named Damien McClusky, who had been strangled in West London, and an unidentified man, who was murdered near Hungerford Bridge over the Thames. In addition to these four murders, Lupo was charged with two attempted murders.
In July 1987, at the Old Bailey, Lupo was sentenced to four life sentences, plus 14 years. Lupo had pleaded guilty to all charges. There were investigations in cities Lupo had visited in the early 1980s, such as New York City, Berlin and Los Angeles, to see if he was responsible for unsolved homicides in those locations, although no evidence of any further crimes committed by Lupo came to light.
In February 1995, Lupo died in Frankland Prison, Co Durham from an AIDS related illness. He had contracted the disease shortly before murdering his first victim and told the police that discovering his medical condition had led to a loathing of fellow homosexuals with him developing a "callous rationale" and an "urge to kill". He spent the last years of his life in a prison hospital.
