Law enforcement conducted a sweeping roundup of drug offenders Tuesday that so far has netted 19 people in Mercer County. Sheriff Ernie Kelty said officers from his agency and Harrodsburg and Burgin police departments got an early start, executing warrants stemming from 34 sealed indictments on drug-trafficking charges. The raids started about 5 a.m., and all those arrested were in custody by 10 a.m.
