Fourteen serving and former police officers have been interviewed again as the investigation into their part in a botched murder probe continues, it has emerged.
Five men, including one from Willenhall, were jailed for the gangland killing of drug dealer Kevin Nunes, aged 20, who was shot at Pattingham, near Wolverhampton, in 2002.
Their convictions were however overturned by the Court of Appeal last year after the release of a report detailing blunders by Staffordshire Police.
The conduct of nine serving and five retired Staffordshire officers during the murder probe is being investigated by the Independent Police Complaints Commission.
Those under investigation include Staffordshire Assistant Chief Constable Jane Sawyers; Marcus Beale, Assistant Chief Constable at West Midlands Police; Northamptonshire Chief Constable Adrian Lee and Gloucestershire Chief Constable Suzette Davenport.
The IPCC today said all 14 people involved had been co-operating in attending for another round of interviews in recent weeks.
Spokeswoman Annabelle McMillan said: “All 14 officers have been interviewed again in recent weeks as part of the ongoing investigation.
“We are presently considering re-interviewing a small number of the officers and hope to make arrangements soon to do so. All the officers, retired and serving, have co-operated in attending for interview.”
The IPCC probe centres on how Simeon Taylor, who claimed to have seen the killing, was dealt with, as well as ‘disclosure issues’ prior to the trial in 2008.
Taylor’s evidence was said to have been ‘vital’ to the case because investigating officers had been met with a wall of silence.
Amateur footballer Kevin Nunes was found dead in a country lane at Pattingham after being shot five times.
The alleged gangsters, jailed for a total of 135 years for the shooting, were cleared in March last year following the revelation of a damning report into the murder probe during a Court of Appeal hearing in London.
The report highlighted a series of failings that led to questions being asked about the reliability of the lead witness, Simeon Taylor.
The men jailed for Nunes’ killing were Adam Joof, of Derwent Close, Willenhall, and Owen Crooks, of Wolverhampton. Also jailed were Levi Walker, of no fixed address, Antonio Christie, of Devey Drive, Great Bridge, and Michael Osbourne, of Hobgate Road, Heath Town.
They were each originally ordered to serve minimum jail terms of between 25 and 28 years.
The murder probe involved about 180 officers. A total of 1,060 statements were taken, and more than 200 pieces of information were received from the public, after media appeals following the shooting.
Ms Davenport is a former Assistant Chief Constable of the Staffordshire force. Following her time there, she transferred to the West Midlands, where she led the force on intelligence and neighbourhood policing. She took up the Gloucestershire Chief Constable role in February this year.
