She went on have a baby son by him, born three months after Paul died.The couple split in 1970 and he never saw Peter again until Mr Booth faced him in court and told the jury what he saw.In graphic evidence, a baby doll was marked up to show the different injuries found on Paul’s body and shown to the jury.Home Office pathologist Dr Mark Egan then hit the doll’s head on a hard surface to show how the skull fracture could have been caused.Dearlove, who had no previous convictions, moved to London after his split with Mrs Booth, and started a new life.He married, had two daughters and is now a grandfather. Dearlove was 21 when he moved in with Carol Booth, now deceased, and her three children, and told the jury he liked them but did not love them. “However, sadly Paul was not given the opportunity to live his life due to the cruel and wicked actions of David Dearlove.”This was a man who entered Paul’s life and was supposedly to act as a father figure to Paul.”A man, who was supposed to care for him and look after him.”Instead of doing this he ended Paul’s life in the most violent way.”The actions of David Dearlove on October 1 1968 not only physically killed Paul but also destroyed his memory.”He was buried into an unmarked grave the location of which remains unknown and he was not spoken about for many years.”However, we now believe as a family that this court case has shown everyone that Paul did live a life and that his memory will never be forgotten.” He and his sister Stephanie Marron also said they had suffered assaults and cruelty at the hands of Dearlove while in the household.

He was also jailed for four years to run concurrently with the life sentence for three child cruelty offences. Mr Justice Males said Peter had been “haunted” by his childhood memories.He said Stephanie had tried to bury the memories but had been forced to relive them when she gave evidence in court. A man who witnessed the murder of his brother when he was three-years-old has been praised for his bravery in coming forwards 49-years later to secure the conviction of his stepfather for the killing having been “haunted” by his memories. Peter Booth went to the police after he became incensed when he saw a photo on Facebook of his little brother Paul sitting on David Dearlove’s knee.The trial heard how Paul was taken ill at his home on Rodney Street, in Haverton Hill, Stockton, on the evening of October 1, 1968.He suffered a fractured skull and bleeding around the brain, and died hours later.The child was in the sole care of Dearlove, who said it was a tragic accident from Paul falling from his bed on to an uncarpeted concrete floor.Police investigated at the time but no action was taken and an open verdict was recorded at Paul’s inquest.But five decades later, Peter came forward and said he had seen Dearlove swing Paul by his ankles and bash his head on the fireplace through the living room door when he went downstairs to get a drink. Outside court, Paul’s family said he would have celebrated his 50th birthday this year but instead he lies in an now-unidentifiable grave at the Haverton Hill baptist church, since closed and demolished.In a statement they said: “Thinking about this makes us sad, as Paul would have been a man, no doubt married and more than likely with children of his own.
