lost in taxi /wallet /Elm Park hospital / Rathfarnham Tue 5th June

My elderly mum thinks she dropped her wallet in a taxi while traveling from St. Vincents Hospital Elm Park to Rathfarnham Wood on tuesday evening 5th June at about 5.30 pm. She sat in the front seat & would have had a walking stick. The driver's name was a Mr. Martin & lives northside . (She remembers the name because my name is Martin ) The wallet was dark brown & contained a large sum of cash & nothing else . It's a long shot but any help appreciated ! Reward of course !!
