Convicted Felon Pleads Guilty to Drug and Ammunition Charges

BOISE – Mathew Grover, 28, of Nampa, Idaho, pleaded guilty today to possession of methamphetamine with intent to distribute and unlawful possession of ammunition, Acting U.S. Attorney Rafael Gonzalez announced. Grover was indicted by a federal grand jury on December 13, 2016.


According to statements made at the hearing, Grover was arrested on October 5, 2016, by Nampa Police officers on a federal warrant for violating supervised release in another federal case. Later that day, United States Probation officers with the assistance of Nampa Police officers searched Grover’s home in Nampa. Among the items found inside the home were $4,709 in cash as well as a plastic bag containing 42.09 grams of pure methamphetamine. In the garage, officers found two rounds of 16-gauge ammunition and five rounds of 12-gauge ammunition. On January 9, 2012, Grover was convicted of conspiracy to participate in a racketeering enterprise and unlawful possession of a firearm. As a result of this conviction, Grover was prohibited from possessing firearms and ammunition. As part of his plea agreement, Grover will be entering admissions to numerous supervised release violations in his 2012 case. Sentencing is set for June 27, 2017, before Chief U.S. District Judge B. Lynn Winmill.


Possession with intent to distribute methamphetamine is punishable by up to twenty years in prison, at least three years of supervised release, and a $1,000,000 fine. The charge of unlawful possession of ammunition is punishable by up to ten years in prison up to three years of supervised release, and a fine of up to $250,000.

The case is the result of an investigation by the United States Probation Office, and the Treasure Valley Metro Violent Crime Task Force. The Metro Task Force was created approximately eleven years ago and is comprised of federal, state and local agencies, including the Federal Bureau of Investigation, Bureau of Alcohol, Tobacco, Firearms and Explosives, Boise Police Department, Ada County Sheriff’s Office, Caldwell Police Department, Nampa Police Department, Meridian Police Department, Canyon County Sheriff’s Office, and Idaho Department of Probation and Parole.
