Family members and friends came to the scene in Colorado Springs to try to account for friends and family after the DEA, alongside various other federal and local law enforcement agencies, raided an "underground nightclub" over the weekend.

The nightclub had moved between several Colorado Springs addresses, but had been inside the building raided by federal agencies on Sunday for several months, officials said.

More than a dozen active-duty troops were at the nightclub during the raid, some as patrons and others working as security guards, the DEA said.
