Bierton bludgeoned the 73-year-old to death with her coffee table in a “brutal” attack at her home in Worksop, Nottinghamshire, in November 2021.
He had been wrongly housed next to her while on licence from a life sentence for murdering two sisters in 1995.
Sentencing Bierton, Mr Justice Pepperall said: “You have been found guilty of the senseless and brutal murder of three elderly and disabled women in their own homes.”
He said Bierton “showed each of the victims no mercy” and the “sustained attacks” included “extraordinary levels of violence”.
He added: “I am left in no doubt whatsoever that you must never again be given the opportunity to walk the streets.
“The only just sentence in this case is that you should remain in prison for the rest of your life.”

A Probation Service representative told the court the decision to grant Bierton, 63, accommodation in Rayton Spur, Worksop, was “incorrect”.
Mr Justice Pepperall said it had been a “significant mistake”.
In his sentencing remarks, the judge said: “That decision was flawed and you should not have been housed among elderly and vulnerable residents.
“Ms Quinn was entitled to expect better, and the system plainly failed her.”
