The man killed in the Beaver Dam apartment building explosion last week was a 28-year-old quality control technician for a food manufacturer there who had a background in science, but his pastor said he “was not a bomb maker.” Benjamin D. Morrow, 28, of Beaver Dam, was killed in the apartment blast, according to Roman Ryan of Joyce-Ryan Funeral Home & Cremation Services in Madison, which is handling Morrow’s funeral arrangements. Law enforcement officials haven’t released Morrow’s name but Beaver Dam Police Chief John Kreuziger said investigators are presuming that the man killed was making bombs when the explosives he was working with detonated accidentally inside the apartment at 109 Knaup Drive.
