A man has been remanded in custody after appearing in court charged with murdering a woman and her son at the home they shared in Oxfordshire.
The bodies of Sally Cox, 43, and 22-year-old Martin Faulkner were discovered in a “horrific scene” at the terraced house in Banbury on Monday.
Michael Kelly was arrested by police at a residential address in Swindon hours after the victims’ remains were found.
The 45-year-old was charged with two counts of murder, Thames Valley Police said.
During a brief hearing at Banbury Magistrates’ Court, Kelly, from Swindon, spoke only to confirm his name and address.
He is due to appear at Oxford Crown Court on Thursday.
Kelly, who wore a light grey tracksuit, is also accused of one count of grievous bodily harm.
This charge relates to a 19-year-old girl who was badly injured in the incident, thought to be Mrs Cox’s daughter Amy.
Two teenagers, said to be Amy and Mrs Cox’s other daughter, 13-year-old Katie, were in the house at the time of the attack but managed to escape.
Amy is in a serious but stable condition at Oxford’s John Radcliffe Hospital, while her sister Katie is “severely traumatised” but had no physical injuries.
A post-mortem examination on Mrs Cox revealed she died of multiple head injuries caused by a “heavy bladed instrument”, a spokesman for the police force said.
Results of her son’s post-mortem are yet to be revealed.
Officers who went to the house were confronted by a “horrific scene”, with two people “obviously dead or very close to death”, Detective Inspector Steve Duffy said.
He added: “All I can confirm is their injuries are consistent with blunt trauma and I can’t say if an axe was used, but a firearm was not used.”
Mrs Cox and her family are believed to have lived in their house for a year.
