Marcus Arduini Monzo, 37, is on trial at the Old Bailey for the murder of 14-year-old Daniel Anjorin during a violent rampage in Hainault, London, on April 30 last year, which also involved attacks on four others. Witnesses described Monzo smiling after slashing a security guard’s neck with a sword, and CCTV footage captured him mounting the pavement and causing chaos. Monzo, who denies the charges, had previously exhibited bizarre behavior, including expressing conspiracy theories and ordering a samurai sword before the attacks.
