A young mother of twin boys was killed in a hit and run in Constance Bay early Sunday. 

Happened around 2am.  Police say the woman (26-year-old Erin Vance) was walking with her boyfriend on Bayview Drive, when an SUV went off the road and struck her.

The driver of the SUV (a 23 year old man) then fled on foot.  He's since turned himself into police and will appear in court Tuesday to face various charges including impaired driving, criminal negligence causing death, and failing to remain at the scene of an accident.
