Kelly Gentry stabbed the victim multiple times after demanding he give her money so she could leave the area.
She had gone to the victim’s home in Wellesley Road on June 23 where the pair began drinking together.
Gentry became aggressive, demanding money and threatening the victim with a knife.
She stabbed the victim in his stomach before taking money and cards from his wallet.
Gentry then stabbed him again in his shoulder and chest before cutting him across his throat after he tried to flee the room.
A woman has been jailed for life with a minimum of six years for stabbing a man in Clacton.
The victim passed out but came to at around 5.30am when he alerted a neighbour who called the emergency services.
Gentry, 47, of no fixed address, was arrested in Harlow on July 1 and was charged with attempted murder the following day.
She denied the charge but was found guilty at Chelmsford Crown Court on Monday, December 11 of causing Grievous Bodily Harm with Intent.
At the same court today (Friday, February 16) she was jailed.
Investigating officer, Detective Sergeant Phil Terry from Clacton CID, said: “This was a horrific attack which left the victim seriously hurt.
“Fortunately his injuries weren’t life-threatening but the reality is that Gentry had tried to kill him and the attack could’ve been a lot worse.
“Gentry is a dangerous woman who was willing to kill someone in order to steal from him and prevent him telling the police.
“I am pleased she is off the streets and is no longer able to pose a threat to the victim or anyone else.
“I want to praise the victim’s bravery throughout the investigation and court process. I hope this sentence provides some solace to him.”
