Both fentanyl enforcement and overdoses are on the rise in Oklahoma, with more than 700 people dying last year from the drug. | MORE | Father fights for justice after son's fatal fentanyl overdoseLeaders have expanded access to Narcan to try to help with the problem, but the amount of product available to Oklahomans has also risen. The amount of fentanyl seized by law enforcement agencies tripled last year. "If you're doing drugs and they're not prescription drugs, you're playing Russian roulette," Keith Montgomery, who lost his daughter to a fentanyl overdose, said. Montgomery knows the dangers of fentanyl all too well. His daughter, Leah Marie, struggled before getting clean in 2016. "I thought all my problems were over," Montgomery said. But 4 years later, the urge of addiction returned. Leah Marie died two nights before her 31st birthday. "The call that no parent wants to hear that she was gone," Montgomery said. "A coworker took her out to have a drink. The coworker had secured some pills, and she gave my daughter one. They never made it out of the parking lot."Leah Marie was one of 137 people killed in Oklahoma from a fentanyl-related death in 2020. The numbers climbed to 743 in 2023. "I have been to probably eight or 10 funerals of people that I know that have lost their children, and I have two friends that lost both their children to fentanyl," Montgomery said. While he sees the loss around him, law enforcement agencies said they are working to crack down on the issue. "We're seeing a lot more of the powder a few years ago," Cleveland County District Attorney Greg Mashburn said. KOCO 5 obtained data from his office that shows fentanyl-related arrests are up significantly, jumping from just 10 in 2021 to 122 in 2023. So far in 2024, there have been 84 arrests. Mashburn said he expects 2024's arrest numbers to pass last year's numbers. District 21's Task Force also saw seizures triple during 2023. There were 65 fentanyl seizures with a total weight of 3,587 grams being confiscated. A dose that is the size of seven grains of salt can be deadly."High demand and high supply, so they can sell it for a lot cheaper, and recently they're selling for $2 or $3," Mashburn said. Montgomery said he feels reassured that law enforcement is taking action, but the illicit drug continues to haunt his life. Three months ago, Montgomery had to use Narcan nasal spray on a woman he found in the alleyway of his business, an action that could have saved his daughter's life. "Her breathing was very erratic. That's when we had the girls bring the emergency drug," Montgomery said. Leah Marie also worked for Hope is Alive, a nonprofit organization that works with those struggling with addiction, up until her death."She loved life. She lived life to the fullest, and I miss her every day," Montgomery said.
