A "dangerous" addict was convicted of murdering his friend at the entrance of a pub in London.
Joe Gynane was fatally wounded at 37-year-old Mohamed Elmi with a large kitchen knife at the entrance of the Coach and Horses pub in Soho on March 3 at around 6:00 GMT.
Hours later, he used the "blood stained blade" to seriously injure a 16-year-old boy near Tottenham Court Road.
Aged 34, homeless, he was convicted of killing Elmi at Old Bailey on Wednesday.
Gynane was also found guilty of inflicting serious bodily harm on the unidentified teenager.
Gynane and Mr. Elmi had spent part of the morning walking together in Soho, smoking and drugging with a group of people, the court said.
The accused admitted to taking heroin, crack and spice.
Attorney Gareth Patterson, QC, told the jury: "In his first knife attack, he killed a man named Mohamed Elmi in Soho.
"During a brief but deadly assault against the threshold of a pub, he stabbed her repeatedly with the help of a large kitchen knife."
The court heard that Gynane was a "dangerous" man, who had already been convicted of robbery and several assaults.
Gynane, of Wimbledon, South West London, denied the murder and inflicted serious bodily injury with intent.
He claimed a reduction of liability on the grounds that he suffered from the "misuse syndrome" – the effects of misuse of drugs – and a personality disorder.
Judge Richard Foster placed the accused in custody and sentenced him on Thursday afternoon.
