A woman must serve four decades in prison for killing an off-duty jailer while driving drunk.

Kellie Lewis was sentenced to 40 years in prison today after pleading guilty to the murder of Tommy Lampkin. Lewis had three previous DWI charges when she struck and killed Lampkin in November 2010.

Toxicology results show Lewis’s blood alcohol level was over three times the legal limit. Lampkin left behind a wife and two children.
