Northern Ireland authorities believe triple murder suspect Ian Rutledge moved back into the Fermanagh home of his wife Vanessa Whyte and their two teenage children after his family became aware of his deteriorating eyesight.

PSNI detectives are investigating whether the suspected triple murder-suicide had been planned in advance by the former truck driver – or whether it was triggered by a dispute in the family home.
