Teen in car with possible guns or drugs reported

I'm not sure whether to classify this as attempt to locate a traffic complaint, but it's a white Chrysler 300, Arizona plates, balance unknown.

RP had very erratic speech all over the place, advised her (number withheld) year old nephew was in the vehicle and he owns a firearm which would be illegal and never leaves it behind.

And because he left without anybody knowing.

She believes the vehicle has guns or drugs in it.
