The man behind the wheel of a car that killed a London mother and severely injured her infant son pleaded guilty Monday to multiple charges in a Waterloo Regional courtroom.

Ahmed Darwish was driving 214 km/hr on Highway 7 in Wilmot Township when he slammed into the car carrying the Dumitru family on the evening of November 27.

​Darwish's Mercedes slammed into the back of the Dumitrus' Mazda, causing it to roll over multiple times.

Susana Dumitru was in the backseat with her then two-month-old son George. Susana was ejected from the vehicle and landed in a grassy ditch. The 29-year old mother died and the baby was rushed to Sick Kids Hospital where he was placed on life support for several weeks to treat a major brain injury.

Darwish was charged with dangerous driving causing death, two counts of dangerous driving causing bodily harm, impaired driving causing death and two counts of impaired driving causing bodily harm.

"This was a serious tragedy and one that could have been avoided," Crown Attorney Michael Michaud said following the hearing.

The court heard that George, now approximately five months old, may never fully recover from the accident and could require assistance his whole life.

Michaud noted that Darwish refused a breathalyzer test at the police station following the accident. In a statement of facts read in court, Darwish refused 17 times to provide a breath sample. The records show he had a previous drunk driving conviction from 2009.

Darwish had also been charged with failing to provide a breath sample and failing to submit to a drug evaluation following the crash.

The Crown will be looking for what Michaud calls "significant penitentiary time," suggesting eight to ten years would suit the crime.

Lawyers are back in court March 16 to select a sentencing date.
