A woman from Santa Rosa is behind bars on suspicion of driving around with more than 70-thousand lethal doses of fentanyl. Forty-five-year-old Amy Mellott was arrested after a traffic stop last Thursday, but police did not release details until Monday. Mellott was also driving several people who were either on probation or had warrants out for their arrests. Police say Mellott, who also had a warrant out for her arrest, was hiding five ounces of fentanyl in her undergarments.
