A convicted double murderer was today jailed for life after he admitted killing a fellow inmate at a maximum security jail 19 years ago.

Peter Brown, 45, murdered fellow prisoner Alvin Bay, 44, at HMP Parkhurst on the Isle of Wight in 1994.

He admitted murder when he appeared on a video link from prison, where he is currently serving a life sentence for killing two people in just six days in 2010.

Brown stabbed Darran Lancashire, 43, at his flat in Kimberley, Notts, on January 6, 2010.

Six days later he knifed 31-year-old Brian Flaherty before strangling him with a wire at his home in Nottingham.

Brown, from Kimberley, hid the bodies and stole from his victims and was found guilty at Nottingham Crown Court in December 2010.

He was given a minimum sentence of 40 years.

Today he was given a life sentence with a minimum term of 11 years and eight months at Winchester Crown Court. It will run consecutively.

He admitted killing fellow inmate Mr Bay at the high security prison in Newport on the Isle of Wight in 1994, when he was in jail for another offence.

Hampshire police launched an investigation in 2012 in response to new information received about the circumstances surrounding Mr Bay's death.

On June 27 this year the CPS authorised Hampshire Constabulary to charge Brown with the murder of Mr Bay.

Detective Superintendent Dick Pearson, of the Hampshire Major Investigation Team, said: "Our thoughts are with Alvin Bay's family while they come to terms with the news that justice has been served in court today.

"We have kept the family informed throughout this prosecution, which has been a profoundly emotional time for them.

"I am grateful for their support and understanding as we sought the answers to solve this case.

"Specialist detectives dedicated their expertise to examine and explore new information through questioning of Peter Brown.

"Other enquiries included analysis of the original post-mortem examination and photographs of where Mr Bay's body was found in the prison in 1994.

"Detectives also visited serving inmates and members of the public who gave information and evidence to the original inquest.

"We appreciate the assistance of the CPS in demonstrating our determination and persistence in pursuing criminals suspected of historical crimes."

Sarah Dineley, District Crown Prosecutor, added: "We have worked closely with Hampshire Constabulary in relation to the murder of Alvin Bay.

"The collaborative working on this 'cold case' throughout the investigation led to new information that provided sufficient evidence for a prosecution against Peter Brown for murder, to be brought.

"Peter Brown today has taken responsibility for his actions in 1994.

"I hope this sends a message that no matter how long ago a crime was committed we will work with the police on obtaining evidence.

"And where there is sufficient evidence and it is in the public interest to do so we will bring a prosecution and seek to obtain justice for victims."
