LAWRENCEVILLE, Ga. AP – Suburban Atlanta dentist Barton Corbin pleaded guilty Friday to killing his wife in 2004 and a girlfriend in dental school 14 years earlier. He was immediately ordered to serve two life sentences in prison for the murders, but would be eligible for parole.

Corbin entered the pleas to two counts of malice murder after four days of jury selection for his trial in the murder of his wife, Jennifer Corbin. He had been scheduled to stand trial later for the 1990 murder of Dorothy “Dolly” Hearn in Augusta, where both Barton Corbin and Hearn where both dental school students at the time.
