The masked teenager who stabbed shop assistant Joan Hoggett to death will be sentenced today.

Ethan Mountain, 19, of Heaton Gardens, South Shields, who was wearing a horror mask and had his hood up, launched a "50 second" attack on Joan Hoggett in the One Stop Shop at Fulwell, Sunderland, on September 5 last year and left her with 29 knife injuries which caused damage to her heart, lung, arteries and intestine.

Mountain, who is currently detained in Rampton top security hospital, admitted manslaughter on the grounds of diminished responsibility.

He had been on trial at Newcastle Crown Court, where prosecutors claimed the killing, which may have been part of a botched attempted robbery, was murder.

But Mountain's legal team claimed the teen was suffering an abnormality of mind at the time of the killing, which impaired his responsibility for it.

Prosecutor David Brooke QC said last week it was now accepted on both sides that Mountain is a paranoid schizophrenic and "very ill".

Trial judge Mr Justice Butcher order the jury to deliver a not guilty verdict in respect of the murder charge.

Mountain's barrister Leonard Smith QC said the teen could face a period of detention or be given a hospital order, which would mean The Home Secretary would have to approve his eventual release.
