Piotr Naja killed sister-in-law Beata Hausner
A man has been found guilty of killing his sister-in-law who died after an argument at his West Midlands home.
Polish national Beata Hausner, 26, died from a serious head injury after the row at Piotr Naja's home in West Bromwich High Street on 14 May.
A jury at Wolverhampton Crown Court convicted Naja, 33, of manslaughter. He was also found guilty of assaulting his wife, Ewa.
Police described Naja as a "violent and dangerous man".
He was remanded in custody ahead of sentencing on 13 March.
Det Sgt Rob Bastin, of West Midlands Police, said Ms Hausner had come to Britain to try to save her sister, who she believed was suffering serious domestic abuse "at the hand of her husband".
Officers said Ms Hausner was attacked by Naja in an "alcohol-fuelled row" and died the following day.
He added: "Today's verdict means that Ewa can continue to mourn her sister, safe in the knowledge that she can come to no further harm."
