Charles Lendelle Carter was recently sentenced to life plus 20 years in prison for the 2005 murder of a Norcross mother of six.

It was the third life sentence for Carter, a former chef whom authorities say is a serial killer. Carter pleaded guilty March 3 to a charge of murder and burglary in Gwinnett County.

Carter was convicted of beating and strangling 35-year-old Angela Thayer Green to death on Dec. 26, 2005. Carter is already serving two sentences of life without parole for fatally stabbing two women in Fulton County.
