Alfie Hammett and Joshua Howell mugshot after Ipswich murder

Alfie Hammett, 19, and Joshua Howell, 18, stabbed Mr Quigley, of Wymondham in Norfolk, in an attack in Westgate Street on January 17 last year. 

At about 3.35pm, the pair encountered Mr Quigley, who was with two friends.

Hammett, of Larkhill Rise, Rushmere St Andrew, and Howell, of Wellington Street, Ipswich, were both wearing face masks and were carrying large knives.

Hammett ran directly towards James and proceeded to attack him, while Howell – brandishing a machete - chased after one of James’ friends, who managed to escape to safety in a nearby shop.

A Home Office post-mortem examination found Mr Quigley suffered four stab wounds to the torso, with two wounds to the chest and abdomen proving to be fatal.

Following a five-week trial, they were both found guilty of the Norfolk teenager's murder.

The pair were remanded in custody pending a sentencing hearing to be held at Ipswich Crown Court on Monday, March 11.
