Vital information about the killing of pensioner Roseann Mallon is only being drip-fed to her inquest, a Coroner's Court has heard.
Accusing the police and Historical Enquiries Team of procrastination, High Court Judge Mr Justice Weir slammed a delay in the disclosure of a report linking the murder weapon to at least six other shootings.
Demanding a report on the gun's history and an explanation for the delay, Judge Weir said: "I want the whole story and I want it now."
The Czech assault rifle has been forensically linked to the UVF murders of Charles and Theresa Fox at Moy, Co Tyrone, in 1992 as well as the murders of John Quinn, Dwayne O'Donnell, Malcolm Nugent and Tommy Armstrong outside a bar in Cappagh, east Tyrone, in 1991.
But Ms Mallon's inquest was only made aware of the link after a member of the HET phoned the Coroner's Service a day after the inquest started four weeks ago, the court was told.
The HET has been aware of the link since August, it was claimed.
Judge Weir said: "We are being fed little bits of information and have been on a repeated basis."
Roseann Mallon (76) was shot by UVF gunmen in May 1994.
