Marshall refused to answer police questions when interviewed
A man jailed for life for murdering a kitchen salesman, cutting up his body and dumping it, has admitted dismembering four other bodies.
Stephen Marshall, 38, of Borehamwood, Hertfordshire, must serve at least 36 years for killing Jeffrey Howe, 49.
He killed Mr Howe in London last March and scattered his body parts across Hertfordshire and Leicestershire.
St Albans Crown Court heard Marshall, who had links to London's Adams crime family, cut up bodies in the 1990s.
Shortly before he was sentenced, his barrister Peter Doyle QC said Marshall had explained to him how he dismembered the bodies of four unidentified men who had been killed earlier.
Detective Superintendent Mick Hanlon, of Hertfordshire Police, said they were now looking into these cases.
Hertfordshire Police said it was likely detectives would visit Marshall in prison to question him about his claims.
Scalp was removed
Marshall said he was working as a doorman at clubs associated with the Adams family between 1995 and 1998 when he was asked to cut up the bodies.

Mr Doyle said he was told the bodies were buried in Epping Forest near London and Marshall thought it "sensible" not to ask questions.
Earlier, the court heard how when Mr Howe's body parts were found, the flesh on his scalp and face had been removed and his ears and tongue cut away. His hands have never been found.
Mr Howe was murdered on 8 or 9 March in his flat in Southgate, north London, the jury was told.
The court heard Marshall had moved into Mr Howe's flat after the pair met through the murdered man's work as a kitchen salesman.
Marshall refused to leave the flat and planned to take over Mr Howe's identity after murdering him, jurors were told.
Prosecutor Stuart Trimmer QC said Marshall and his girlfriend Sarah Bush, 21, paid no rent to Mr Howe and stole his food and began to use his bank account.
Marshall had originally denied murder but changed his plea at the end of the third week of his trial.
Bush was jailed for three years and nine months after admitting perverting the course of justice. A charge of murder against her was withdrawn.
Mr Justice Cooke told Marshall: "(Mr Howe) looked up to you and was scared of you and the evidence is you exploited that.
"You took advantage of Mr Howe in life and then after his death you used his money."
Mr Howe's family said they would remember him for his "larger than life personality and generosity".
They added: "We are still finding it extremely difficult to come to terms with Jeffrey's death and the macabre actions of those who killed him.
"No mother should ever have to contemplate her son being treated in such an inhumane manner. It is something which we will never be able to comprehend.
"We didn't even get a chance to say goodbye to Jeff and that is one of our deepest regrets."
