A sexual predator branded a "danger to any woman" has been jailed for at least 38 years for murdering Zara Aleena as she walked home from a night out.
Jordan McSweeney, 29, admitted killing and sexually assaulting the 35-year-old law graduate in Ilford, east London, in a late-night attack in June.
She was savagely kicked and stamped on by McSweeney, who had followed a number of other women that night.
His refusal to be in the dock showed "no spine whatsoever", the judge said.
In a televised sentencing, Mrs Justice Cheema-Grubb told the Old Bailey that McSweeney – who would not come up from the court's cells – had carried out the attack with "sickening deliberation".
Killed Walking Home

Giving him a mandatory life sentence, the judge said she did not believe McSweeney's actions on the night of the killing were an "aberration". She described him as a "pugnacious and deeply violent man".

Mrs Justice Cheema-Grubb said of the attack: "It was a steep and sudden escalation of violence that had simmered in his life for many years."
McSweeney was also given a four-year term for sexual assault, a sentence that will run concurrently.
The defendant, from Dagenham in east London, had only recently been released from prison when he carried out the attack.
He had 28 convictions for 69 crimes, dating back to 2006, ranging from burglary to assaulting the police and including racially motivated offences.
In 2010, when he was a teenager, McSweeney was convicted over an attack on a young woman he had left with a swollen eye. Eleven years later, he was made the subject of a restraining order that barred him from contacting another female victim.

McSweeney was caught on CCTV following other women before attacking Ms Aleena
The Old Bailey heard how Ms Aleena was discovered by a couple on a driveway on Cranbrook Road in the aftermath of the 26 June assault, which began at about 02:15 BST. She was partially naked and struggling to breathe, having sustained 46 separate injuries in the nine-minute beating.
The 35-year-old received medical treatment for more than an hour on the street before she was taken to the Royal London Hospital. She died later the same morning.
Prior to the killing, McSweeney had been caught on CCTV drunkenly lurching in the street after being ejected from a pub for pestering a female member of staff.
He went on to follow three women and confronted a fourth before he targeted Ms Aleena.
Speaking outside the Old Bailey, Ms Aleena's aunt Farah Naz said McSweeney's sentence would protect the public from a man who "cannot and must not live freely in the world".
She added that his "extreme indifference" to her niece's life and the law made him a "very dangerous man".
Ms Naz said: "Today, like every day, we live with the horror that she faced.
"We are deeply touched by the kindness we have felt from so many and this is testament to the power of Zara's spirit."

The Old Bailey was shown CCTV footage of the attack – McSweeney's reason for not appearing in court was that he did not "want to relive" what happened that night, his defence barrister George Carter-Stephenson KC said.
Ms Aleena's family left the courtroom while footage of her final moments was shown.
The Old Bailey heard how after the fatal assault, McSweeney took away some of Ms Aleena's clothes, keys, phone and purse – possessions he later discarded.
Prosecutor Oliver Glasgow KC said McSweeney had "treated Zara Aleena's belongings with the same appalling disdain with which he had treated her life", casting them away like "any other insignificant piece of rubbish".
After the sentencing hearing, Det Ch Insp Dave Whellams described McSweeney as "not a sophisticated criminal".
The detective, who led the murder investigation, said: "This was a ferocious and repetitive attack that shocked even experienced murder detectives.
"He attacked Zara out in the open on a residential street and, other than a clumsy effort to hide a bag containing his belongings, he did not try to cover his tracks."
