The driver accused in a hit-and-run that killed a pregnant woman and her unborn child has pleaded not guilty.

Prosecutors say 27-year-old John Sudac of Carlsbad left the scene, after causing the deadly accident on Interstate 5 in January.

Sudac faces manslaughter and hit-and-run charges and could face up to 11 years in prison if convicted.

Meantime, there was a separate investigation into the victim's stolen purse - a case that was dismissed after the purse was found.
