 A D.C. man has been convicted of first-degree murder and rape in the killing of a Maryland woman in 1979. The murder case of 28-year-old Vicki Lynn Belk went unsolved for almost 45 years before DNA helped crack the case. A jury found 63-year-old Andre Taylor guilty on all counts Friday after two hours of deliberation and a nine-day trial in Charles County, Maryland. Belk was living in Suitland with her boyfriend and worked at the U.S. Department of Agriculture at the time of her murder.
