> White also responded to media inquiries about a neighbor’s report of the sound of a generator and an odor of burning rubber coming from the couple’s fourplex in the 3000 block of Deakin Street. Sounds like they were likely running a laser cutter and the "generator" sound was actually an air compressor. (These are used to blow the smoke out of the way of the beam so that you get a cleaner, more accurate cut.) Chlorine gas is a major risk with a lot of materials, but presumably there could by other kinds of nasty fumes depending on what they were cutting. edit: others are saying that it was in fact CO, so I'll go with that. I'd still like to know what they were cutting, though.
