Marijuana business raids tied to investigation of Colombian drug cartels

Colorado marijuana businesses raided this week by federal agents are being investigated for a possible connection to Colombian drug cartels, sources told our partners at The Denver Post on Friday.

Three sources, who have knowledge of the investigation, spoke on condition of anonymity because they are not authorized to speak.

Investigators believe the businesses that were raided are all "one big operation," a source said.

Federal agents swarmed 14 locations, including dispensaries and grow warehouses, in Denver, Commerce City and Boulder County, according to sources. Two homes were targeted.

Investigators believe those targeted in the raids had been actively purchasing area dispensaries and growhouses over a sustained period of time, one of the sources said.
