Arthur’s stepmother Emma Tustin was jailed for life with a minimum of 29 years in December last year for murder, while his father Thomas Hughes was jailed for 21 years for manslaughter. The pair appealed against their sentence – which was also referred to appeal court judges for being unduly lenient. Judges have extended Hughes’ prison term by three years, to 24 years, while Tustin’s remained unchanged. Tustin and Hughes were convicted of killing the youth, who suffered a non-survivable brain injury while in Tustin’s care. The child, from Solihull in the West Midlands, was poisoned, starved and beaten by Tustin, 32, and Hughes, 29, in a protracted campaign of abuse. Court of Appeal judges also reviewed Jordan Monaghan’s sentence. He was given three mandatory life sentences and ordered to serve a minimum term of 40 years at Preston Crown Court in December after murdering two of his children and his new partner. The 30-year-old blocked the airways of Ruby, 24 days old, and Logan, 21 months, in January and August 2013. While on police bail six years later, he killed his new girlfriend, Evie Adams, 23, with a drug overdose in October 2019. The verdicts for Hughes, Tustin and Monaghan were handed down along with other verdicts for Wayne Couzens, who murdered Sarah Everard, and Ian Stewart. Stewart, who murdered his wife and fiancee six years apart, could one day be freed after appealing his life sentence. He killed 51-year-old children’s author Helen Bailey in 2016 and was found guilty of her murder in 2017. After that conviction, police investigated the 2010 death of Stewart’s first wife, Diane Stewart, 47, and in February he was found guilty of her murder. Double killer’s appeal against life sentence heard by five senior judges and reduced He will now serve a minimum term of 35 years. Couzens was jailed for life for the rape and murder of Ms Everard, 33, who he abducted in south London on March 3, 2021. It was the first time such a sentence had been handed down for a murder of an adult that was not committed during a terrorist attack. Appealing the term, Couzens’ lawyers argued he deserved “decades in prison” but said a life sentence was too much. But on Friday, the Lord Chief Justice, Lord Burnett, and four other judges refused to reduce his sentence.
