In high school, Ashley Delgado dreamed of becoming a doctor and one day buying her father a Rolls-Royce. “She wanted to heal people,” said her father, James Taylor. She had a high GPA, Taylor added, and did especially well in science and Latin.

In her mid-20s, Ashley suffered a leg injury and was prescribed OxyContin. The painkiller marked the beginning of a yearslong descent through addiction — from prescription opioids to methamphetamine, then heroin, and finally, fentanyl.

With her family’s support, Ashley spent time in a rehabilitation facility in her hometown of Cleveland, and in recovery she moved into a sober living home. But on an early summer morning in 2023, Ashley’s body was found on a dead-end street just outside the city. One sandal was missing. Tucked inside her bra was a folded scrap of paper containing a tan powder. She was 29.

“I have lost my father, my grandmother — that hurts,” Taylor said. “But when you lose your child, that’s the worst thing on the planet, because they’re not supposed to go before you.”

Toxicology tests would later show a mix of substances in Ashley’s system, including protonitazene and metonitazene, powerful synthetic opioids from a little-known class of drugs known as nitazenes. Her death was ruled accidental.
