ADA, Okla. (KTEN) — District 22 district attorney Erik Johnson's drug and violent crime task force, with the help of Ada Police, busted a fentanyl ring Monday afternoon that lead to three arrests.

"Pure fentanyl-- it's highly dangerous,” Johnson said. “Fentanyl is here. It's in our communities and it's something that every prosecutor across the state has to deal with."

A three-month long investigation resulted in the arrests of Tyler Campise, James Knight and Marissa Kuper.

Campise was arrested at his workplace, a metal scrapyard in central Ada, with 10 grams of fentanyl in his possession.

20 grams of fentanyl was seized between the three arrests.

"The initial focus of this investigation was Tyler Campise,” Johnson said. “My task force has been working an angle on him the last couple of months. We believe that at least two of these individuals involved were large-scale distributors of fentanyl in our community."

According to Johnson, the 20 grams of fentanyl is equivalent to about 20 sugar packets you'd find in a restaurant, and could kill about six thousand people.

"We've seen some increases in fentanyl around with simple possessions,” Ada police chief Carl Allen said. “We knew it was in town. I have one officer that has three different saves, where he saved people that were in some kind of cardiac distress."

District attorney Johnson says Ada PD's work with his task force was crucial in completing the fentanyl bust.

In addition to the distribution of fentanyl charge for all three suspects, Marissa Cooper is also facing a child endangerment charge for having her infant child in her vehicle while completing a fentanyl transaction.

Fentanyl is approximately 100 times more potent than morphine and 50 times more potent than heroin as a prescription pain reliever, according to the Drug Enforcement Administration.
