They were all booked under 152.025.2(1).
.2 is the subdivision and 1 is the section. The portion in question:
Subd. 2 Possession and Other Crimes:
A person is guilty of controlled substance crime in the fifth degree and upon conviction may be sentenced as provided in subdivision 4 if:
(1) the person unlawfully possesses one or more mixtures containing a controlled substance classified in Schedule I, II, III, or IV, except cannabis flower, cannabis products, lower-potency hemp edibles, or hemp-derived consumer products or a residual amount of one or more mixtures of controlled substances contained in drug paraphernalia; or"
I think likely it's a 'constructive' possession as I doubt each of the three had cocaine on their person.
As for the booking listing 1,2,3,4, I think that's just how they book all drugs charges, every other drugs charge booked that day lists 1,2,3,4 as well, except for one which is in weight (Possess 25 grams or more). I would say odds are there was just one drug and I'd bet it's Cocaine. Most likely Cops searched a house or car after being tipped off on something obvious (coke) and found something obvious (coke)
Caveat of that same statute:
"(a) A person convicted under the provisions of subdivision 2, clause (1), who has not been previously convicted of a violation of this chapter or a similar offense in another jurisdiction, is guilty of a gross misdemeanor if: (1) the amount of the controlled substance possessed, other than heroin, is less than 0.25 grams or one dosage unit or less if the controlled substance was possessed in dosage units; or (2) the controlled substance possessed is heroin and the amount possessed is less than 0.05 grams."
So if it is coke and they had .25 per person (.75 total) then they get a misdemeanor. Otherwise it's a felony, and up to five years maximum, or a fine, or both.
