Jake Fahri was born in 1989 in London, England, and lived in Lee, a neighborhood in southeast London. From a young age, Fahri displayed troubling behavior and developed a history of criminal activity. By the time he was 19 years old, he had already accumulated multiple convictions, including armed robbery, assault, and burglary.

His earliest recorded offense occurred in 2004, when he participated in a knife-point robbery of a schoolboy at a train station. Over the next two years, Fahri continued to engage in violent behavior, including assaulting a girl in the street and committing burglary. Despite interventions by the courts, including referral and supervision orders, his behavior escalated.

The Mizen family had previous run-ins with Fahri. Years before the murder, he had harassed Harry Mizen, Jimmy’s older brother, on two separate occasions. The Mizens reported his behavior to police and his school, but Fahri continued to be a threat in the local area.

By 2008, Fahri had developed a reputation for aggression and unpredictability. He had not turned his life around, and instead continued to intimidate others in the community. His eventual encounter with Jimmy Mizen would prove to be deadly.

On May 10, 2008, the day after his 16th birthday, Jimmy Mizen entered the Three Cooks Bakery on Burnt Ash Hill in Lee, southeast London, with his brother Harry. Around 11:30 AM, Jake Fahri, then 19, entered the shop and immediately confronted the Mizen brothers. Fahri began making threats, apparently continuing a pattern of hostility from years before.

Jimmy, known to be calm and gentle despite his large build, standing 6'4" and weighing 14 stone (89 kg), refused to be intimidated and declined Fahri's challenge to step outside. Humiliated, Fahri launched a violent and chaotic attack inside the bakery. He first struck Jimmy with plastic drink bottles, which led to a struggle that caused all three to crash into a glass cake display. Fahri was temporarily pushed out of the shop.

Moments later, Fahri returned with a metal advertising sign, which he used to prod at Jimmy. Jimmy grabbed the sign, and in response, Fahri picked up a 12-inch hot glass dish from the shop counter and hurled it at Jimmy's face. The dish shattered on impact, and a 1.5-inch shard of glass sliced through Jimmy’s neck, severing major blood vessels including the carotid artery and jugular vein. Witnesses reported that Fahri fled the scene grinning.

Jimmy, bleeding profusely, staggered into a back cupboard to hide, fearing a second attack. His older brother Tommy found him there, but Jimmy collapsed in his arms. Their mother, Margaret Mizen, arrived shortly after and fainted at the sight of her dying son. Jimmy succumbed to his injuries on the scene.

Fahri turned himself in to police three days later. During questioning, he admitted he threw the dish but denied intending to kill Jimmy. At trial in March 2009, the jury found Fahri’s story unconvincing and unanimously convicted him of murder. He was sentenced to life imprisonment with a minimum term of 14 years.

In November 2009, while incarcerated, Fahri was stabbed in prison by fellow inmate Sean Mercer, who was serving time for the murder of 11-year-old Rhys Jones. Fahri survived the attack.

In June 2023, Fahri was released on licence, having served the minimum portion of his sentence. However, in January 2025, he was recalled to prison after it was discovered he had released a drill rap track referencing Jimmy Mizen’s murder, a clear breach of his licence conditions. The public and the Mizen family expressed outrage, especially Jimmy’s mother, who was shocked by Fahri’s attempt to gain notoriety through music referencing her son’s death.
