A man has been jailed for life for beating his teenage ex-girlfriend to death with a dumb-bell in the presence of their young daughter.
Jack Wall, 22, murdered Amelia Arnold, 19 on November 7 last year, after she ended their relationship following his "consistent and persistent" abuse.
Wall used "terrifying force" as he attacked her in the home they shared in Stevenage, Hertfordshire, after she threatened to report him to police for assaulting her, Blackfriars Crown Court was told.
He fractured her skull by hitting her with a dumb-bell before stuffing a sock in her mouth, fearing she was still alive, the hearing was told.
Wall's uncle, Joseph Potter, then helped his nephew dump Miss Arnold's body in a shallow grave in Travellers Lane, Hatfield.
She was found in woodland four days after being reported missing. A post-mortem examination revealed she died as a result of head injuries.
Wall, of Hadrian's Walk, Stevenage, denied murder but was found guilty by a jury last week.
He was jailed for 19 years, along with a four-and-a-half-year sentence for obstructing a coroner, to run concurrently.
Judge Aidan Marron QC told him: "You took a life. You also deprived your child of a devoted mother.
Potter, from Sycamore Avenue in Bletchley, was jailed for two and a half years for assisting an offender and obstructing a coroner.
