WICHITA, Kan. (KWCH) – Statistics for Sedgwick County provide insight into the scope of the fentanyl crisis in south-central Kansas. About 80% of drug overdose deaths in Sedgwick County are fentanyl-related. While that number may seem high, the joint Wichita-Sheriff’s Office Narcotics Unit has seized about 750,000 fentanyl pills so far this year. Statistics show that fentanyl is here and the reality of that is far from letting up.
