A Sacramento man known as "Dr. Death" has been indicted by a federal grand jury for illegally selling guns and other dangerous weapons.

The six-count indictment charges 45-year-old Daniel Crowninshield with unlawfully manufacturing and dealing in firearms, possessing a firearm after having been previously convicted of a crime of domestic violence, and possessing machineguns and unregistered firearms.

He was arrested today in Sacramento by ATF special agents.

According to court documents, Crowninshield, who was also known by his online moniker "Dr-Death," operated an unlicensed firearms manufacturing business out of C&G Tool, a metal shop in North Sacramento.

The indictment alleges Crowninshield did not conduct background checks or enforce waiting periods before selling guns.
