A man has appeared in court charged with murdering his former partner and her son at the home they shared.
Sally Cox, 43, and Martin Faulkner, 22, were attacked with a "heavy bladed instrument" at the house in Banbury, Oxfordshire. They were found on Monday.
Michael Kelly, 45, of Hatch Road, Swindon, appeared before Banbury magistrates and was remanded in custody.
He also faces one charge of causing grievous bodily harm.
Mr Kelly spoke only to confirm his name at the hearing. He was arrested in Swindon a few hours after the bodies were found in Mold Crescent.
Thames Valley Police said a post-mortem on the body of Martin Faulkner found he died as a result of multiple sharp weapons injuries.
Officers said a 19-year-old girl who was also at the house remains in Oxford's John Radcliffe Hospital where her condition is improving.
