Sarah Barrass (35) and her half-brother Brandon Machin (39) were sentenced by Sheffield Crown Court to life in prison with a minimum term of 35 years. Barrass and Machin had each admitted two counts of murder, conspiracy to murder six children, and five counts of attempted murder.
The couple lived together in Sheffield with their six children. The sexual relationship was a secret one and Barrass presented herself as a single mother supported by her brother. The children were unaware that Machin was their father. Barrass had reportedly told them that their father had died during the second world war.
