From staff reports OKLAHOMA CITY – Three Oklahomans have been sentenced for their roles in distributing fentanyl that resulted in an overdose death.
Kalub Lynn Robinson, 30, of Blanchard, along with Joseph Preston Anderson, 37, and Tiffani Amber Stevens, 31, both of Oklahoma City, all pleaded guilty.
Court records show that beginning in at least September 2023, Anderson and Stevens engaged in a conspiracy to distribute fentanyl to others.
On Dec. 3, 2023, the two distributed fentanyl powder to Robinson, and Robinson distributed that fentanyl to another person the next day, which led to the victim’s death. Public record further reflects that, despite knowing of the overdose death, Anderson and Stevens continued to sell fentanyl through January 2024.
Anderson and Stevens were charged with a drug conspiracy in May 2025 and pleaded guilty. On Oct. 22, 2024, Robinson was charged with distribution of fentanyl, and he, too, pleaded guilty.
At their sentencing hearings on Sept. 15, Oklahoma Western District Judge David L. Russell sentenced Anderson to serve 15 years, Stevens to serve six years, and Robinson to serve five years, in federal prison.
Each of the defendants also was ordered to pay $2,725.60 in restitution, a total restitution award of $8,176.80.
This case was investigated by the Drug Enforcement Administration, which pointed to its “One Pill Can Kill” campaign.
