A Petone man who decapitated his elderly neighbour believed he was responsible for his being evicted. Eugene Baker has admitted murdering 71-year-old Francis Tyson in November last year. Both men dealt synthetic drugs from their Jackson Street Housing New Zealand flats. In the days leading up to the killing, Baker had a number of arguments with Tyson around dealing. He believed the pensioner was an informant for Housing New Zealand and was to blame for his eviction notice. The 42-year-old will be sentenced in June.
