BRITAIN'S most wanted fugitive - double murder suspect Kevin Parle - could be dead, a former Met Police detective who has vowed to track him down has claimed.
Peter Bleksley, who until February was also the host of Channel 4 reality TV show Hunted, today said he wanted to bring Parle in "dead or alive".
Last week Essex News and Investigations told how double murder suspect Kevin Parle was now Britain's most wanted man following the capture of murder suspect Shane O'Brien.
Parle is suspected of shooting dead 16-year-old Liam Kelly in 2004 and Lucy Hargreaves, 22, a year later.
He has been on the run for more than 13 years, but alarmingly Merseyside Police, which wants to question him about two murders, refused to issue any fresh media appeals when contacted by this website, and Mr Bleksley said the force would not officially cooperate with him.

Mr Bleksley today held a press conference during which he warned Parle "I am coming for you" and that "his days were numbered".
He said: "So what will happen in a year? Will he still be on the run? Will we discover a corpse?
"As there is one school of thought that he could be dead - but dead or alive, I want to find him."
Mr Bleksley said the self-funded search was not an ego trip, but he is penning a book about the hunt.
He said: "Essentially I will have a pen, a notebook, a mobile phone and a business card.
"But I've also got social media, I've got a network of former cops, former military and people in the private investigations world."

He said police appeals were often one-dimensional and he wanted to put more flesh on the bones about the 6ft 5in, privately-educated suspect.
He also said that Merseyside Police had refused to cooperate with him over the hunt and relatives of the victims have yet to speak to him.
He plans to blitz social media with appeals for information and tonight travelled to Liverpool to put flyers and posters up asking for information on Parle's whereabouts.
He said: "He could be anywhere, but I will do my utmost to find him.
"He has been living a charmed life and his profile is not as high as I would like it to be, but I would like to change all that.
"This is the best possible use of my skills, my experience, my contacts and my following, it is the best possible thing I can do."
MURDERED: Lucy Hargreaves (Merseyside Police)
Ms Hargreaves was shot dead on a sofa after three men burst into her home in Walton, Liverpool, on August 3 2005.
The living room and hall were then set on fire with petrol.
It is believed Lucy's partner Gary Campbell, was the intended target, but he escaped the flames by jumping from upstairs with his daughter.
No one has been convicted over the murder.
Police also want Parle, now 39, and also known as Joseph Kenneth Parle, in connection with the murder of 16-year-old Liam Kelly in the early hours of June 19 2004 in Dingle, Merseyside.
SHOT: Liam Kelly (Merseyside Police)
Police believe the teenager was approached by two men from different directions, both armed with guns.
Although he tried to run and get into a house, he was shot in the chest and arm and died at the scene from a chest injury.
Three other people have been convicted over the Killing, but it is suspected Parle was involved.
Parle has blue eyes, ginger hair and a one inch scar on the left side of his head.
Liverpool John Moores University produced a series of images of what Parle may look like now.
The last potential sighting was made by police in Perth Western Australia in 2015.
Detectives initially believed Parle fled to the US, but then the Costa Blanca area of Spain, after there were possible sightings in autumn 2005 in the Torrevieja area.
The tourist-hotspot region of Alicante was also thought to be another possibility, but Parle has been able to stay one step ahead of investigators.
CAPTURED: Shane O'Brien (Romanian Police)
O'Brien was caught after an international manhunt of more than three years.
O'Brien, 31, appeared at Westminster Magistrates Court on April 6 after being extradited from Romania after he was captured in Cluj-Napoca on March 23 and was remanded in custody.
He was charged with the murder of Josh Hanson, 21, from Kingsbury, north-west London, who died at RE Bar in Hillingdon, west London, in October 2015 after being stabbed in the neck.
