Prosecutors said Monday they have dismissed the cases of three people arrested for distributing and selling crack cocaine.
Alaska, California and Texas all charged the defendants with conspiracy to distribute and distribute crack, a class D felony, while Texas charged them with possession with intent to distribute a controlled substance.
They were arraigned in federal court in Philadelphia.
Prosecutors said the defendants planned to sell the cocaine for more than $3,000 a kilo to drug dealers and users in Philadelphia and other parts of the country.
Prosecutors said they were also selling crack in the same way.
The defendants were arrested last year after police in Pennsylvania and Texas found methamphetamine, heroin and other drugs in their vehicles and a truck in Anchorage, Alaska.
