A woman arrested last year in Georgia for a 1987 stabbing in Columbus has pleaded guilty to a murder charge and been sentenced to 15 years to life in prison.
50-year-old Zina Roberson was sentenced in Columbus Monday. She originally was indicted on a more serious count of aggravated murder. Investigators linked her DNA to evidence taken from the Columbus apartment where 77-year-old Anna Mae Florence was killed. Police at the time said Roberson knocked on Florence's door, claiming she was soliciting money for a charity benefiting the elderly.
