A retired detective has told the Morris tribunal that he found a key witness at the tribunal "most unreliable" when he interviewed him in 1999 and 2000.
Retired detective Richard Caplice told the tribunal how he interviewed Mr William Doherty as part of the internal Garda investigation headed by Assistant Commissioner Kevin Carty following the McBrearty family's complaints of Garda harassment following the death of the Raphoe cattle dealer Mr Richie Barron.
Mr Caplice said Mr Doherty told him that two Raphoe gardaí, Det Sgt John White and Garda John O'Dowd, put pressure on him to ensure that a friend of his, Mr Noel McBride, would maintain a story that he saw Frank McBrearty jnr and his cousin Mark McConnell on the night Mr Richie Barron died.
The ex-detective said he believed Mr Doherty's motivation for telling him this was that he "liked to be the centre of attention, even if it was negative attention".
Mr Doherty also made allegations about meetings with Supt Kevin Lennon and the two officers, Mr Caplice said. "I felt he wasn't telling the truth and he was making a lot of it up. I found him most unreliable. He couldn't be consistent from day to day."
