Sentence: 49 months imprisonment and banned from driving for seven years and two weeks
Mary McCann was driving a Vauxhall Astra with three children while under the influence of alcohol. At around 11.10pm on August 9, 2021, on the M1 near Milton Keynes, between junctions 14 and 15, she was driving at 72mph in a 60mph zone. Her car drifted into the lorry's lane, leading to a collision that caused her vehicle to spin. Her children, four-year-old Lilly McCann and 10-year-old Smaller Peter McCann, were not wearing seatbelts; Lilly was thrown from the car and found on the roadside, while Smaller was flung around the backseat and found slumped in the footwell. Both children died at the scene. A two-year-old girl passenger was not badly hurt, and the lorry driver, Simon Denton, suffered whiplash.
