VIDEO: While details still are not quite clear surrounding a fatal explosion March 5 at Village Glen Apartments, authorities are extremely clear on one point. "No known link to terrorism at this time — but we are still investigating," Beaver Dam Police Chief John Kreuziger said Monday during a news conference. The department also would not confirm whether the person renting the apartment was the man killed in the explosion, as the blast itself is making it difficult for authorities to identify the individual, Kreuziger said.
