Four years on and no answers for Tina Satchwell's family

Tina Satchwell, from Youghal Co Cork, hasn't been seen for four years.

Every time Teresa Dingivan’s phone rings her heart skips a beat, hoping for one second that it will be her beloved sister Tina Satchwell who vanished four years ago today.

Whenever she sees a blonde woman on the street, she snaps to attention, always reflexively primed to find her.
