It will be 20 years on Friday, December 4th since Sandra Collins disappeared in Killala, Co Mayo.

Despite a fleece jacket being found by the local pier, it’s believed that she didn’t take her own life by jumping into the sea but was rather abducted, murdered and buried in a shallow grave.

Her brother Patrick believes someone is harbouring a secret as to what happened to her that night and he’s begging them to just let the family know where she is buried.

On Wednesday, which is National Missing Persons Day, Patrick Collins joined Kieran on The Hard Shoulder.

As well as that, Geoff Knupfer is Chair of the Independent Commission for the Location of Victims Remains, and explained what the response is when a person disappears.
