According to the DEA, these potentially deadly imitations are manufactured predominantly in Mexico to look like the real thing.

One of the most lethal knock-offs are fake oxycodone pills, which the DEA says can kill. The agency claimed more than a quarter of the these pills tested contained a deadly dose of fentanyl.

Plaquemines Parish Sheriff’s Office said the fentanyl contained in the fake pain pills is becoming a major public safety hazard.

The PPSO has arrested 22-year-old Franklin Senfles, who allegedly sold pills that killed BCHS senior, Hailey Deickman.

Senfles is charged with Second-Degree Murder and Attempted Second-Degree Murder.
