Murder accused was likely not under influence of cannabis - toxicologist

A clinical toxicologist has given evidence at the Central Criminal Court that a Westport man accused of murdering his wife was likely not under the influence of cannabis at the time of her death, despite a long history of drug use. James Kilroy, aged 50, has pleaded not guilty by reason of insanity to the murder of Valerie French Kilroy at their home in Kilbree Lower between 13 and 14 June 2019. Dr Johann Grundlingh told the court that whilst Mr Kilroy's urine tested clear of cannabis two days after the killing, chronic exposure to the drug may have triggered a psychotic episode in a vulnerable person. The witness stated that intoxication from cannabis typically lasts hours rather than days. Under prosecution cross-examination, Dr Grundlingh acknowledged it remained possible Mr Kilroy had consumed cannabis after his last admitted use on 7 June. The trial continues before Mr Justice Paul McDermott and a jury.
