20-year-old Peter Sutcliffe met 16-year-old Sonia Szurma, the daughter of Ukrainian and Polish refugees from Czechoslovakia, at Royal Standard pub on Manningham Lane in Bradford's red light district. Sonia married Peter William Sutcliffe on 10 August 1974, her 24th birthday, two years after she began treatment for schizophrenia. When she found out that she could not have children due to previous miscarriages she went back to studying to be a teacher.[citation needed] Her relationship with her husband was later characterised by the writer Gordon Burn as domineering, with Sonia willing to slap him down "like a naughty schoolboy". When her husband was found guilty of the murder of multiple women in 1981, Sonia remained married to him and continued to live in their Bradford matrimonial home. They separated around 1989 and divorced in July 1994 on grounds of unreasonable behaviour.
