Missing black Samsonite suitcase

Please help me share my mother’s story. A friend of hers was en route returning my mother’s wedding outfit (White short sleeved top with V detail at the neck; Rose Gold Pleated Skirt; matching rose gold coloured bag and jewellery of sentimental value). It was Saturday 20th of October, she got on a dublin 15 bus from Connolly south bound at approximately 12.20. She placed a black samsonite cabin sized case into the case rack beside the bus driver. There was a similar case already there (not Samsonite). A gentleman disembarked at Eden Quay lifting the Samsonite case leaving the wrong case behind. Would feel it was a genuine mistake. CCTV footage has been sent to Ringsend headquarters and Rathfarnham Garda station so you can contact either places if you have any information. Not only that you can private message me here on facebook. Very anxious to retrieve this case so please please share this story.
