A man who uses several different aliases is being sought by police in connection with a murder that occurred in St Albans over two decades ago.

Paul Milburn, 43, of Surrey, was killed in Noke Lane at about 4.25pm on Monday April 26 in 1993.

He died in his car following a single gunshot.

Police are seeking Justin Martin Clarke, 59, in connection with the murder and have today (Monday) launched a new appeal for information.

Detective Inspector Justine Jenkins, from the Beds, Cambs and Herts Major Crime Unit, said: “Justin Clarke uses different aliases including Martin Maher and Justin Martin, among other variations and combinations of his name.

“He has links to Birkenhead, Oxfordshire and London, as well Ireland, Croatia and Qatar.

“We have wanted to speak with Justin Clarke in connection with the murder of Paul Milburn for a number of years now.”

She added: “We would like to speak with anyone who has any information about his current whereabouts. We’d also like to hear from anyone who believes they have come into contact with him.

“Anyone who sees Clarke should not approach him but should contact police immediately via 999.”

A spokesman for Herts Police said that two decades ago four people were arrested following Mr Milburn’s murder.

Their charges ranged from conspiracy to deceive, conspiracy to handle stolen goods and conspiracy to handle supplied controlled drugs.

But no one was charged for Mr Milburn’s murder.

Following a television appeal about Clarke on Crimewatch on BBC One last Tuesday (26), information passed on by several callers is currently being examined by detectives.

Anyone with any further information in relation to Clarke’s current location or movements should contact the Major Crime Unit via 101. Alternatively people can contact Crimestoppers, the independent charity, anonymously on 0800 555 111 or through the secure online form at www.crimestoppers-uk.org
