Swerlein will be formally charged Friday, possibly for possession of explosive devices after authorities removed more than 400 chemicals from his Longmont home over the weekend.
Boulder County Deputy District Attorney Katharina Booth raised questions about whether Swerlein was just an eccentric backyard scientist or a danger to the community.
In his home, Swerlein had a pound of sodium azide - a material so dangerous that 5 grams caused an explosion that damaged a University of Colorado lab...
In addition to the chemicals, Booth said authorities found books with titles such as Don’t Get Mad, Get Even; Your Revenge is in the Mail, and Home-made Explosives.
