An Independence man is among 11 people facing federal charges in connection with selling 150 kilograms of methamphetamine and 10 kilograms of heroin in a conspiracy that federal officials say ran for three years.

Authorities also seized 77 firearms as well as a World War II gas grenade during their investigation.

Cory Matthew Jobe, 27, of Independence was indicted along with six residents of Kansas City, one Liberty resident, one Riverside resident and two others. Jobe faces a charge of possessing 500 grams of meth and one kilogram of heroin to distribute and a charge of being a felon in possession of a firearm.

A federal grand jury returned a 22-count indictment, under seal, in December. The U.S. attorney for the Western District of Missouri made them public Monday following arrests and defendants’ initial court appearances.

All 11 defendants are accused of participating in a conspiracy to distribute meth and heroin, and of money laundering. Federal authorities say that happened from the beginning of 2017 until the middle of last month. Authorities want the defendants to forfeit $1.7 million – proceeds of the drug sales at a street price of $250 for an ounce of meth and $1,200 for an ounce of heroin.
