ASHLAND A bad batch of drugs â suspected of being a heroin/fentanyl mix â is believed to be killing users in Boyd County. Boyd County Coroner Mark Hammond confirmed Tuesday six to seven deaths in the Ashland city limits and Boyd County are believed to be attributed to drug overdoses. With toxicology results two to three weeks out, Hammond said his office could not conclusively rule the deaths drug-related, but other factors point to it. According to Hammond, the influx of drug overdoses began last Tuesday or Wednesday and was killing people at a rate of about one a day. Monday marked the first day in which no deaths were reported, Hammond said.
