A man guilty in the drunk-driving deaths of a young woman and a pregnant teenager in Prince Albert has been sentenced to four years in federal prison.

Jeremiah Jobb, who pleaded guilty in May to two counts of impaired driving causing death for his role in the July 2013 crash that killed 21-year-old Taylor Litwin and 17-year-old Brandi Lapine, was sentenced Friday in a Prince Albert court.

Court heard he was speeding at 150 kilometres per hour in a 50-kilometre-per-hour zone and that his blood-alcohol level was more than twice the legal limit during the collision.

Lapine was pregnant at the time of the crash. Her unborn child survived but was three months premature.

The girl was named Aurora Sky. She suffered a head injury during the car wreck while she was still inside her mother's womb. She spent five months in Saskatoon's Royal University Hospital, where doctors eventually placed a shunt in her head to drain fluid off her brain.

The child suffers from seizures and uses a feeding tube, according to her grandmother. She’s still learning to move her arms and legs.

Doctors say the girl is likely to have some form of disability for the rest of her life.

Jobb, who had no criminal history prior to the crash, apologized in court to the victims’ families.

He won’t be allowed to drive for two years following his release from prison.
