Casefile - The Steak Knife Murderer

A woman who stabbed her boyfriend in the chest with a steak knife was been jailed for life for his murder.

Emma-Jayne Magson, 23, killed James Knight, 26, in the early hours of 27 March 2016 following a "drunken row".

Magson, who was found guilty after a three-week trial, was sentenced at Leicester Crown Court and ordered to serve a minimum of 17 years.

Judge Nicholas Dean QC said her behaviour was "inexplicable".

She later claimed she had stabbed Mr Knight in self-defence but refused to give evidence during the trial.

The judge said: "You did nothing to help James Knight. Your behaviour is inexplicable.

"You knew you had used the knife, the knife you disposed of. You carried the bloodied T-shirt into the house and there it was on the floor, close to where James remained prone, struggling by now to breathe.

"You have demonstrated no real remorse for what you did, on the contrary you have effectively blamed James Knight for what you did".

Magson refused to give evidence during her trial but the court heard that she claimed Mr Knight had been beaten up by two bouncers on a night out in the city centre.

The victim's brother Kevin Knight, who lived a few doors away, helped Magson carry the body back into her front room - without knowing about the fatal stab injury.

He was later woken by Magson banging frantically on the door screaming "It's James, it's James, he's dead, he's dead", the jury heard.

In his closing speech, prosecutor Michael Evans QC said: "(On that night) she was in drink, she was cold, she was brutal, she was manipulative, she was calculating, she was volatile, she was determined and she was vicious."

KFS’s Coventry scientists examined items from the scene for blood, Ms Magson’s and Mr Knight’s clothing for blood and conducted a damage assessment on Mr Knight’s clothing to determine how any damage could have been caused.

In summary, blood matching Mr Knight was found on:

• The blade of a knife found in a wheelie bin outside the scene;

• On Ms Magson’s clothing;

• A towel from the scene;

• A swab from the scene.

A damage assessment on Mr Knight’s clothing showed a single stab cut through both his t-shirt and hoodie. These areas of damage aligned with each other.

Our team in Coventry also conducted footwear mark analysis and concluded that there was some association between Mr Knight’s right shoe and the scene mark on the front door of the address.
