"Have I killed someone?" asks blackout fatal crash driver

A blackout sufferer who caused a fatal collision knew it was unsafe for her to be driving despite being granted a driving licence, a court has heard.

In October 2010 47-year-old Mary McLaughlin suffered a blackout behind the wheel of her Vauxhall Zafira. She ploughed into the back of a Ford Focus after failing to stop at a roundabout on the M5, killing 26-year-old student Rebecca McManus.
