The family of a missing Mayo woman is calling for an inquest into her disappearance 16 years ago.

29 year old Sandra Collins disappeared from her home on December 4th in 2000.

In 2014, a 50-year-old man accused of her murder was acquitted after a judge ruled there was not enough evidence to convict him.

Sandra's family have provided new video footage of her enjoying a day out as they try to discover what happened to her.
