Gardaí in Ballina have renewed their appeal for information regarding Sandra Collins who has been missing from Killala, Co Mayo, since December 2000.
Ms Collins, who was born in 1971, was last seen in the town of Killala on December 4 2000 at approximately 11.15pm at the local takeaway, The Country Kitchen.
She is described as 5ft in height with a small slim build, with short brown hair with red highlights. When last seen Ms Collins was wearing black trousers, a maroon polo neck jumper, a beige sleeveless jacket with a hood, and black boots.
As a result of recent public appeals a number of new witnesses have come forward.
Gardaí now believe that a white van was in Killala around the time Sandra Collins was last seen and are now seeking the assistance of the public in identifying this van.
Anybody who may have seen or have information in relation to a white van in Killala on Monday night, December 4 2000, is being asked to come forward and make contact with investigating gardaí at Ballina Garda Station on 096 20560, the Garda confidential telephone line 1800 666 111, or any Garda Station.
