A 15-year-old boy who murdered his mother with a hammer and set her body on fire has been detained for a minimum of 16 years.
Daniel Bartlam had denied murder but admitted the manslaughter of his mother, Jacqueline Bartlam, following a row at their Nottinghamshire home.
Nottingham Crown Court was told she had been beaten seven times with a claw hammer, fracturing her face and skull.
A soap opera murder plot and violent TV clips were found on Daniel's computer.
Reporting restrictions preventing identification of the teenager were lifted by the court following his sentencing.
Mrs Bartlam, 47, was discovered by fire crews at her home in Georgia Drive, Redhill, Nottinghamshire, in the early hours of 25 April 2011.
