Sten Adolf Reinhold Fransson (11 May 1934 – 29 September 2012) was a Swedish man notorious for committing multiple murders, including a triple killing in 1975 — an incident that later became known in Sweden as the Vattnäs Drama (Swedish: Vattnäsdramat) — and the murder of his wife in 2012. Born in Strömsund, Jämtland County, Sweden, Fransson came from a large family and began his military career around 1950 at the Bergslagen Artillery Regiment in Kristinehamn.
