A split-second decision can change lives forever. In one-punch manslaughter cases, a single impulsive blow, perhaps thrown in anger, fear or misguided bravado, leads to a tragic death. These ‘death by a single punch’ incidents are more common in the UK than many realise. Dozens of families every year are left devastated, with one family grieving an unimaginable loss, and another family shocked and fearful as their loved one faces a homicide investigation for an outcome no one intended. It’s a tragic reality, one moment of anger, one fatal assault involving a single blow, and two lives (and families) ruined.
