A woman thought she was going to die when a killer began strangling her in her bed.
David Alty was previously convicted of manslaughter after beating his dad Edward Hall to death with his own walking stick. His history of violence has now continued with an attack that only stopped when he was hit in the groin.
Liverpool Crown Court heard today, Friday, that the victim, who the ECHO has chosen not to name, has known the now 36-year-old since he was a child and "regarded him as a little brother". Alty began living with her in May this year when he "had nowhere else to go".

Cheryl Mottram, prosecuting, said: "It was without problem when he was sober. But it was a different story when he had been consuming alcohol."
And "matters came to a head" in the late evening of June 26 after Alty, of Ford Lane in Litherland, had visited a shop and returned with several cans of lager. The woman took some from him, while he was also "upset in relation to an issue with his son".
The father began shouting at her and accused her of calling him a "nonce". Alty punched a door before grabbing her and hitting her in the face, knocking her to the floor and causing her to lose conciousness.
The woman phoned her uncle for help after coming around, but the defendant overheard the conversation and "started flipping out". He resumed his attack by jumping on top of her on her bed, putting his hands around her neck and squeezing while telling her he was going to kill her.
She "couldn't breathe and thought she was going to die" but managed to knee Alty in the testicles and punch him in order to stop the assault. The police then arrived at the scene after being called by her uncle.
The complainant suffered bruising to her face and arms, and later received treatment in Aintree Hospital for an injury to her wrist. After his arrest, Alty claimed that she was his girlfriend while the "allegations were false and another male was responsible for her injuries".
In a statement which was read out to the court on her behalf, the victim said: "I believe David needs psychiatric support rather than incarceration. I am in fear of harassment and violence from David - I'm not even able to have my son in case anything happens."
Alty, who appeared in court via video link to a mental health treatment centre, suffers from paranoid schizophrenia and was experiencing a "psychotic episode" at the time. He has a "significant history of offences of violence", as well as a "history of substance abuse".
Judge Neil Flewitt imposed a hospital order after Alty admitted assault occasioning actual bodily harm. He was also handed a restraining order preventing him from contacting the victim for 10 years.
His most serious conviction came in 2006, when he was jailed for three-and-a-half years from the manslaughter of his own dad. Mr Hall, 56, was left with 100 separate injuries at Alty's hands.
Known as Neddy, he was described as a "psychopath" who had subjected his son to years of verbal abuse. The pair were living together at a flat on Church Walk, Bootle, at the time
Neighbours heard them arguing on March 15 2005 before, at around 9.30pm, Alty knocked on the door of one "panicking". He said he could not wake his father up, and Mr Hall was found dead in his bedroom.
He initially claimed that another man had attacked him, but later pleaded guilty to the charge - having assaulted him with the mobility aid and kicked and stamped on him. Charles Chruszcz QC, defending, told the court 16 years ago: "The deceased would drive his son to extremes of anguish and behaviour."
Alty was also convicted of assaulting Mr Hall with the walking stick, which he used due to spinal problems, a year before his death. Judge Henry Globe QC, the then Recorder of Liverpool, said upon sentencing: "You have been significantly traumatised and had carried traumatic memories of childhood.
"This was a grave and vicious attack. The extent of the violence was horrific."
