Second victim Gordon Boon had convictions for sex offences
A double-murderer has been jailed for the rest of his life by a judge who told him he was "a very dangerous man".
Royston Jackson, 43, of Pettus Road, Norwich, was convicted of murdering sex offender Gordon Boon, 73.
He strangled Boon and dumped his body in a lane at Great Witchingham, Norfolk in 2008, two years after being released from prison for the first murder.
Jackson killed Stephen Raven in Essex in 1989 and dumped his body in the same way, Norwich Crown Court heard.
Both of Jackson's victims had been strangled and their clothes had been interfered with, before their bodies were dumped in a quiet lane.
The men had been with the defendant on the night before they were killed, the juries were told.
Mr Raven's body had been dumped near Dagenham. Jackson later served 16 years in jail for his murder.
William Taylor QC, defending Jackson, said he had nothing to add after the verdict was read out.
Mr Justice Underhill said: "This was a shocking murder. You are evidently a very dangerous man.
"I am obliged to pass a sentence of life imprisonment on you and you will spend the rest of your life in jail.
"The early release system will not apply in your case."
In the lead up to Boon's murder, the two men had met at a bail hostel in Norwich following Jackson's release from prison. Both men had moved out to separate properties shortly before Boon's death.
Prosecutor Timothy Spencer QC said Jackson murdered Boon, who lived at Westwick Street in Norwich, by strangulation on 3 October and his body was found three days later.
He told the jury that only Jackson knew why Boon was killed.
"We suggest that a possible motive is that there is some sort of sexual overtone given Mr Boon's state of undress," he added.
