DENVER -- Raids in Colorado medical marijuana operations are leading many to wonder if it's part of a much bigger federal investigation.
Details are starting to emerge about possible ties to organized crime.
A dozen marijuana operations were raided Thursday in metro Denver. Federal agents and local police conducted the operations.
They seized millions of dollars worth of pot and property. Officials are still tight-lipped about their investigation.
But one day after the raids, there are rumors about ties to Colombian drug cartels among other things.
