Crossbow death 'largest' murder hunt
"Police said someone on the island probably held the key to why and how Mr Corrigan was killed.
"I do believe the answer is out there amongst the public, and I would appeal for anyone that has any information regarding that - no matter how insignificant - to come forward," said Det Ch Insp Brian Kearney, who is leading the investigation.
Asked whether Mr Corrigan had been deliberately targeted, the detective said: "We continue to keep an open mind regarding the full circumstances, and until we know and establish the full facts - I am unable to say."
The victim had been a photography and video lecturer in Lancashire before retiring to the island about 20 years ago."
"North Wales Police said it had been speaking to crossbow specialists, manufacturers and retailers as part of the inquiry, in an attempt to track down the weapon used."
