A broken, unburned Molotov cocktail was found on the sidewalk. Earlier in the day, two possible explosive devices were found underneath and near a car that was a few blocks from the location of the broken incendiary device. With a hope of a possible connection, the remnants of the bottle and the two strips of towel-like cloth that were in the neck of the bottle were recovered as evidence. The strips had been soaked in accelerant and still smelled strongly of gasoline. The items were M-Vac sampled and a mixture of at least 4 potential contributors was obtained. The major contributor was determined and loaded into CODIS. There was a match. The investigation team now has a potential connection. The take away for us is that the M-Vac successfully collected DNA material from fabric soaked in accelerant.
