 Well, D.C. police have cracked a cold case that dates back 45 years thanks to DNA. Took Charles County jury just two hours last week to convince 62-year-old Andre Taylor in the killing of 28-year-old Vicki Lynn Belk back in 1979. Sergeant John Elliott, a Charles County Sheriff's Office detective, tells NBC4. We learned Taylor's DNA was in a national database because he was arrested for several violent crimes which occurred in Washington, D.C.
