Kansas City, Kan. ? Forty-three people were indicted Tuesday after an investigation into two separate drug rings that authorities allege distributed more than $12 million worth of cocaine, crack and other drugs in northeast Kansas and the Kansas City area.

The investigation, dubbed “Operation Stonewalled,” resulted in the seizure of nearly 43 pounds of cocaine, $335,000 in cash, 18 vehicles and 18 weapons, said U.S. Attorney Eric Melgren.

One of the indictments focused on a drug ring that operated in Leavenworth, Atchison and the Kansas City area, while the second focused on a group that worked mostly in just the Kansas City region, Melgren said.

Arrests in the case began Tuesday morning and 31 suspects were in custody Tuesday afternoon, he said. Suspects were mostly from Leavenworth, Atchison, Topeka and Kansas City, Kan.; Lee’s Summit, Mo., Independence, Mo., and Kansas City, Mo.
