Mother’s Fight After Son’s Tragic Knife Death

A 17-year-old convicted of fatally stabbing 22-year-old John McNab in Leith has been sentenced to life with 17 years minimum, sparking profound grief for his mother Lisa Petrie, who says no sentence can ever heal their loss. John, described as funny and peaceful, had no history of trouble — making his death all the more senseless. Lisa, now a fierce advocate against knife crime, is pushing for tighter knife sales controls, wider access to bleed kits, and harsher bail conditions for weapon offenders — especially after learning the teen was on bail for a prior knife incident when he killed her son. She vows to keep fighting in John’s name, determined to prevent other families from enduring the same unimaginable pain. Support the show:Get a discount at https://solipillow.com/discount/dnn.
