THE mother of a convicted killer who drowned earlier this year had toxic levels of alcohol in her blood, an inquest has heard.
The body of Susan Killeen (54), originally from Hyde Road in Limerick city, was recovered from the canal at Locke Quay in Limerick on May 1.
At the time of her death, Ms Killeen's son Nathan (24) was on trial at the Special Criminal Court along with Wayne Dundon (36) for the murder of Roy Collins in April 2009.
Both men were later convicted of the murder and sentenced to life in prison.
The Coroners Court yesterday heard a statement from Ms Killeen's daughter Ciara that revealed her mother was drinking heavily before her death.
Ciara Killeen, who is a partner of convicted murderer John Dundon (31) - currently serving life for the murder of rugby player Shane Geoghegan - said her mother was "not in a great place mentally".
"There was a lot going on and she was dealing with a lot. She was paranoid to go out of late."
Ms Killeen had been living with Ciara for three years.
Ciara Killeen told gardai that her mother had consumed a bottle of vodka before she left home on the night of the drowning.
She also recalled how her mother had a pillow and a bulky looking bag with her when she said she was going to a friend's place.
Ms Killeen left at 9.30pm and that was the last time her daughter saw her alive.
Following a post-mortem, the pathologist concluded that death was due to drowning secondary to toxic levels of alcohol.
The pathologist said there was evidence of paracetamol and anti depressants in Ms Killeen's system but added that these were below the therapeutic level.
Garda Brian Duddy said he responded to a call at Locke Quay at 12.30am where a woman was seen entering the water.
The woman was seen floating face down and her body was recovered. A bottle of Bushmills and Xanax tablets were found nearby.
Det Sgt Ronan McDonagh recognised the body as being that of Susan Killeen, the inquest heard.
Coroner John McNamara said his verdict is one of accidental death.
