A federal grand jury returned a one-count indictment today against Dequan Lamar Mitchell, 22, of Vallejo, charging him with being a felon in possession of a firearm, U.S. Attorney Eric Grant announced.
Release Date
02/12/2026
According to court documents, Mitchell murdered a man when he was 16 years old and was convicted of murder. Because of that prior conviction, Mitchell is prohibited from possessing firearms. While on probation for that crime, investigators discovered Mitchell was involved in posting a firearm for sale in an illicit gun trafficking app. When police searched Mitchell’s mother’s home, they discovered a loaded Glock 23 handgun with an extended clip. That gun was the same gun Mitchell offered to sell for $1,200 in the gun trafficking forum. Subsequent investigation revealed that the gun was stolen from a carjacking victim in October 2025.
The Solano County Sheriff’s Office, the Solano County Probation Department, the Federal Bureau of Investigation, and the Bureau of Alcohol, Tobacco, Firearms and Explosives are conducting the investigation. Assistant U.S. Attorney Jason Hitt is prosecuting the case.
If convicted, Mitchell faces a maximum statutory penalty of 15 years in prison and a $250,000 fine. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.
This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime.
