Aaron McDermott, 33, was sentenced at Dublin Circuit Criminal Court for offences committed at Beaumont Hospital on April 7, 2021. The defendant pleaded guilty to the unlawful seizure of a vehicle by force or threat, as well as three counts of making threats to kill or cause serious harm to the driver and two children. Judge Elma Sheahan imposed a sentence of nine years, with the final 12 months suspended on the condition that McDermott engage with The Probation Service for 12 months upon his release. He was also disqualified from driving for two consecutive terms of ten years in relation to dangerous driving and driving without insurance.

Judge Sheahan described the dashcam footage as harrowing and noted the severe psychological trauma inflicted on the family, including PTSD and financial distress. While acknowledging McDermott's difficult early life and addiction issues, the judge highlighted his 125 previous convictions and disregard for road traffic laws. McDermott expressed remorse in a letter to the court, stating he was determined to turn over a new leaf.
