A Mayo man who murdered his mother while high on drugs has failed to have his conviction overturned on appeal.
Celyn Eadon of Derrycrieve, Islandeady, Castlebar claimed he was suffering from a mental disorder, as a result of his many years of drug abuse.
Mr Eadon admitted stabbing his mother Nóirín 19 times at their home in Castlebar on Mar 9 2011, but contested the murder charge claiming his drug habit, which began when he was just 10, had caused brain damage.
He further claimed he wasn't capable of forming the necessary intent for murder because he was so intoxicated at the time.
But following a ten-day trial in 2014, the jurors rejected his arguments and convicted him of murder.
Today, his appeal was rejected by judges at the Court of Appeal.
