Mum-of-two, Melissa Liddle was stabbed 40 times by her boyfriend Anthony Ross.
The 23-year-old died following the frenzied attack at their home in March 2015.
Ross pleaded guilty to manslaughter on the grounds of diminished responsibility and was sentenced to a hospital order after doctors concluded he was suffering from paranoid schizophrenia - although prosecutors had argued he should receive a prison sentence.
Melissa’s body was found by her brother Liam who, haunted by her killing, later committed suicide in a double tragedy for the devastated family.
Ross had phoned his mother around the time he killed Melissa on March 15, saying he’d heard voices in his head and had a devil on one shoulder and an angel on the other.
Melissa’s mum became worried when her daughter failed to contact her on Mother’s Day and sent her partner and son to the home on Oak Avenue, South Shields, where the couple lived.
After forcing entry, Melissa’s brother made the gruesome find.
She had suffered 35 knife injuries and there had been at least 41 applications of a sharp object, the court heard.
Melissa’s mum, Tracey Keighley, was on the phone to her son when he found his sister’s body.
