"Why" is a common question among the parents and family members of people lost to America's illicit drug de jour, the powerful opioid fentanyl. Answers are hard to come by. Harder still is figuring out what to do about it. Carrie Walker is one of those parents but she has decided on a path forward. Her eldest son, Alexander Cullers, died of an opiate overdose in 2014 at the age of 18. He'd taken some prescription oxycodone from his girlfriend's grandmother's medicine cabinet. Losing a son would devastate any mother. But then in April 2019 Walker's other son, Andrew Cullers - by then 18 himself - died of an overdose too. In his case, fentanyl, counterfeit oxycodone.
