Past of double murderer Peter Brown to be investigated
The background of a man jailed for murdering two "vulnerable" men in Nottinghamshire is being investigated to see if he committed other crimes.
On Monday Peter Brown, 42, of Main Street, Kimberley, was given a minimum of 40 years for stabbing Darran Lancashire, 43, and Brian Flaherty, 31.
Brown denied the murders but admitted a series of robberies and assaults in the days before the killings.
Detectives said Brown's motives had never been fully explained.
The body of Mr Lancashire was found at his flat in Kimberley on 6 January. Mr Flaherty's body was discovered at his home in Lenton, Nottingham, six days later.
As well as being stabbed, Mr Flaherty had been strangled with a ligature.
Brown hid the bodies and stole from his victims.
The investigating team said Brown had never offered information about why he had killed the men.
They described him as a "serious, serious offender" who often carried a knife and went out equipped to commit violent robberies.
Det Ch Insp Tony Heydon said: "We are open-minded to things he might have done in the past.
"He has spent a long time in prison and we will continue to look at Mr Brown, and the public of Nottingham can be reassured we will do all we can to investigate his criminality."
He added: "We are happy that we have managed to take a really dangerous man off the streets of Nottinghamshire."
