Two people have been charged after an FBI raid on a Hungry Horse home turned up an alleged cache of drugs and a grenade launcher.

Misty Leanne Beck, also known as Misty Leanne Maddox, and Neal Allen Maddox were arrested Jan. 5 in Ravalli County by a U.S. Marshal.

Beck and Maddox pleaded not guilty at an arraignment Jan. 7 in federal court in Missoula.

While the charges date back to January, federal law enforcement officials would not discuss the case, or even if there was an arrest, until recently.

Both Beck and Maddox were charged with conspiracy to distribute methamphetamine, possession with intent to distribute meth, possession of a firearm in furtherance of a drug trafficking crime and felon in possession of firearms. The charges come with a maximum penalty of life imprisonment, a $10 million fine and more than five years supervised release.

Maddox was convicted of a felony in 2011 and Beck was convicted of several felonies, with the earliest in 2002.

They allegedly possessed firearms including a Spikes Tactical grenade launcher and a M1911 pistol. They allegedly possessed and planned to distribute 500 grams of a substance containing a detectable amount of meth from about December 2014 to June 2015 in Flathead County. Five hundred grams i s a little more than one pound.

If convicted of the offenses, they have to give up any property that came from the proceeds of distributing meth and was used to commit the crimes, including firearms and ammunition.

Beck was released without bond to her home in Hungry Horse. She’s required to remain law-abiding and promised to appear in court as required.

Maddox requested to be released in March, but the court required him to remain in detention because there was no way to assure that he would not harm others and return to court as required. The firearms and explosives were found in his home where children lived and releasing him would jeopardize their safety, according to court documents.

Also, he had violated probation when facing less serious charges, and the court believed that the potential life sentence of the current charge provided greater incentive for him to flee.

The jury trial was originally set for March in Missoula, but was postponed with a court order for three months.

More details in the case are federally sealed until the trial.
