OKLAHOMA CITY – JOSEPH PRESTON ANDERSON, 37, and TIFFANI AMBER STEVENS, 31, of Oklahoma City, and KALUB LYNN ROBINSON, 30, of Blanchard, have been sentenced for their roles in distributing fentanyl, the use of which resulted in an overdose death, announced U.S. Attorney Robert J. Troester.
According to public record, beginning in at least September 2023, Anderson and Stevens were engaged in a conspiracy to distribute fentanyl to others. On December 3, 2023, the two distributed fentanyl powder to Robinson, and Robinson distributed that fentanyl to another person the following day, the use of which led to the victim’s death. Public record further reflects that, despite knowing of the victim’s death, Anderson and Stevens continued to sell fentanyl through January 2024. Anderson and Stevens were charged with a drug conspiracy in May 2025 and have pleaded guilty. On October 22, 2024, Robinson was charged with distribution of fentanyl, a charge to which he has since pleaded guilty as well.
At their sentencing hearings on September 15, 2025, U.S. District Judge David L. Russell sentenced Anderson to serve 180 months, Stevens to serve 72 months, and Robinson to serve 60 months in federal prison, followed by three years of supervised release for each. The defendants were also each ordered to pay restitution in the amount of $2,725.60, amounting to a total restitution award of $8,176.80. In announcing his sentences, Judge Russell stated that the circumstances were “tragic beyond belief” and expressed that the world must know that there are significant consequences for dealing fentanyl.
This case is the result of an investigation by the Drug Enforcement Administration (DEA) and demonstrates the importance of the DEA’s “One Pill Can Kill” campaign.
