A man has been found guilty of murdering his girlfriend with a lump hammer in her bed at their flat.
James D'Arcy is due to be sentenced on Friday for killing Hayley Dean at their bedsit in Bournemouth in September 2016.
D'Arcy, 50, of Derby Road, had previously admitted manslaughter, Winchester Crown Court was told.
Ms Dean, 38, died after D'Arcy hit her over the head. He had admitted to police: "I smashed her head in."
Det Insp Neil Phillips, of Dorset Police's Major Crime Investigation Team, said: "James D'Arcy carried out a sustained and brutal attack on Hayley Dean as she lay helpless in her bed."
The court heard D'Arcy could not remember the attack as he was heavily under the influence of alcohol.
A post-mortem examination found Ms Dean died as a result of severe head injuries, sustaining fractures to her skull and swelling to the brain. The prosecution claimed D'Arcy killed her during an argument.
The jury heard that D'Arcy carried out a number of "normal tasks", such as getting onto a bus, withdrawing cash, buying food and topping up his mobile phone, before he told anyone about Ms Dean's death.
