The torture and death of a man whose headless body was dumped in a lake has been branded "depraved" by a judge as he sentenced six members of the same family.
Judge John Bevan QC made the comments at Luton Crown Court as he jailed three members of the Watt family for life for murdering Michael Gilbert and three other defendants for familial homicide.
The 26-year-old was kept as a slave and tortured for his benefit money before being killed. His headless body was dumped in the Blue Lagoon in Arlesey, Bedfordshire, last year.
James Watt, 27, his girlfriend, Natasha Oldfield, 29, and his brother Richard's girlfriend, Nichola Roberts, 22, were jailed for life for murder.
Watt will serve a minimum of 36 years, Oldfield a minimum of 18 and Roberts a minimum of 15.
James's brother, Robert Watt, 20, and his mother, Jennifer Smith-Dennis, 58, were jailed for eight years and 10 years respectively for familial homicide. A third brother, Richard Watt, 25, who previously pleaded guilty to familial homicide was sentenced to six years in prison.
