U.S. Sentencing Commission Report Breaks Down Federal Contraband Sentences
by Chuck Sharman
On February 4, 2026, a federal indictment was unsealed against California state prison guard Matthew L. Madsen, 39, alleging that he accepted over $100,000 in bribes to smuggle contraband cellphones and tobacco into the Salinas Valley State Prison. The guard had been relieved of duty a year earlier when the allegations first surfaced, as reported elsewhere in this issue. [See: PLN, Mar. 2026, p.62.]
His was but the latest example of a problem that drew the attention of the U.S. Sentencing Commission (USSC), which published its own research into sentences for contraband on June 11, 2025. Reviewing the sentences handed down to 852 people between 2019 and 2023 under Sentencing Guidelines §2P1.2, the report found that prison staffers, like Madsen, were the source of 38.6% of contraband cellphones and 18.4% of contraband drugs. Staffers were blamed for no contraband weapons, 97.4% of which were homemade by the prisoners from whom they were confiscated, the report said.
Outside accomplices provided 45.6% of contraband cellphones, including 21.4% thrown over or through a prison fence and 7.1% flown in by drone; another 10% was smuggled by visitors, and 7.1% was sent through the mail. An additional 5.7% were labeled “homemade,” though exactly how a prisoner constructs a cellphone was not explained in the report. Of the remaining 15.8% of contraband cellphones, nearly one-third—2.9%—were brough into a lockup with an incarcerated person and discovered while he or she was being processed or booked.
Of smuggled contraband drugs, outside accomplices provided 57% of the total, including 38.3% from visitors and 23.3% sent through the mail; 5.4% were tossed over a fence or dropped by drone. The remaining 24.6% included 7.8% that were in the incarcerated person’s possession at booking and 6.3% that were considered homemade.
“Individuals with weapons received the highest average sentence of 20 months,” the report noted, compared to a 16-month average sentence for those caught smuggling drugs and five months for those nabbed with contraband cellphones. Overall, the average sentence for contraband possession was 11 months. Sentences fell within the guidelines range for 80.4% of those handed down for contraband cellphone possession. But the share falling within the guidelines range dropped to 53.4% for contraband drugs and 45.7% for weapons. In both cases, it was far more likely that sentences fell below the guidelines range than above—41.4% v. 5.2% in the case of contraband drug terms and 50% v. 4.3% in the case of contraband weapons.
Prisoners and detainees with little or no criminal history accounted for just 8.4% of those sentenced for contraband cellphones and 16% of those sentenced for contraband weapons but 23% of those sentenced for contraband drugs—perhaps reflecting that demand for drugs is typically driven by factors less within a person’s control.
More than half (53%) of those sentenced for contraband weapons were caught “through a physical search of the person’s body,” the report noted. On the other hand, “surveillance tools” such as video and call monitoring or scanners were considered “important” for contraband detection in 27.6% of cases involving drugs and 21.4% of those involving cellphones.
The report covered only those incarcerated in the federal system, including the Bureau of Prisons and the U.S. Marshals Service, which contracts much of its detention space in county jails. See: Special Edition QuickFacts on Prison Contraband, USSC (June 2025).
