Falkirk man William Finlay (57) admitted killing 44-year-old Fiona McDonald, also known as Canning, in her Carmuirs Avenue flat in November last year.
Sentencing Finlay at the High Court in Glasgow today, judge Lady Stacey told him: “Nothing can take away the grief her family feel. Her mother, daughter and grandchildren have been deprived of her company.
“It is not up to me to decide when, if ever, you will be released, that is up to the parole board.”
