Police in Bullitt County raided a meth lab at a home where a toddler had been living.
They charged Elizabeth Singleton, Anthony Robards and Glen Miles with criminal conspiracy to manufacture methamphetamine.
Members of the Bullitt County Drug Task Force say they found ingredients to make more than 50 grams of meth in the Shephersville home.
Two of the suspects arrested are the parents of the 3-year-old girl.
