"Almost every investigation I do results in a fentanyl pill seizure," explains Phoenix Police Officer Kenneth Silvia, who works on the department's Neighborhood Enforcement Team.
According to Phoenix Police, in the Desert Horizon precinct alone, which covers the northern part of the city, officers have already seized 1.9 million fentanyl pills by Aug. 31 of this year.
As if fentanyl wasn't dangerous enough, now, they're finding rainbow-colored fentanyl pills around the city, potentially making it more marketable for kids.
