12 Nov
Summary
- Former soldier stabbed love rival 3 times, killing him
- Attacker was on bail for previous knife attack at time of incident
- Victim's family devastated, says he had high hopes for the future

In a tragic incident, a former soldier named Kai Sainz-Stafford has been sentenced to 5 years and 2 months in prison for the manslaughter of Sam Siviter. The attack occurred on May 1, 2025, while Sainz-Stafford was out on bail for a separate stabbing incident from the previous September.
According to the court proceedings, Sainz-Stafford, 24, had been exchanging "flirty messages" with Siviter's ex-girlfriend, Hannah Cottrell, and had gone to her house late at night to meet her. When Siviter, 35, also arrived at the property, an altercation ensued, and Sainz-Stafford stabbed him three times - once in the leg, once in the knee, and fatally through the heart. Siviter died in the ambulance on the way to the hospital.
Sainz-Stafford initially claimed self-defense, but later pleaded guilty to manslaughter. The judge emphasized the devastating impact of Siviter's death on his family, including his two young sons who must now grow up without a father. Siviter's mother, Glynis Taylor, expressed her unimaginable grief, saying the loss feels like a "life sentence" for the family.
While the sentencing may provide some closure, the tragic incident has left an indelible mark on all those involved. The case serves as a stark reminder of the dangers of violence and the lasting consequences it can have on individuals and their loved ones.
