A bit morbid, but there’s https://en.m.wikipedia.org/wiki/List_of_unusual_deaths. Features stuff like:
Sergio Millán, 59, was alone in his apartment in Torreforta, Tarragona, Spain, when an explosion in a petrochemical plant 3 kilometres (2 mi) away launched a one-ton iron plate into the apartment above him, causing the ceiling to collapse, killing him.
or
Vladimir Likhonos, 25, a student of Kyiv Polytechnic Institute from Konotop, was killed when his chewing gum exploded. Likhonos had a habit of dipping his chewing gum in citric acid to increase the gum’s sour taste. On his work table police found about 100 grams (3.5 oz) of unidentified explosive powder which he used for chemistry studies at home. It resembled citric acid, and it is thought that he confused the two, having accidentally coated his gum in the explosive powder before chewing it. The explosive was found to be four times stronger than TNT, and the explosion was possibly triggered either by reacting with Likhonos’s saliva, or the pressure exerted by him chewing on the gum and explosive powder.
How would they have deducted from his exploded skull that the cause was chewing gum dipped in explosive powder? That is some incredible forensic work. Or maybe they had cameras?
Well when you find a guy with an exploded face, it obviously warrants some further Investigation. I could imagine them looking for a bullet and not finding any, then investigating further. The info about him dipping his chewing gum in citric acid might have been given by friends, they also found the explosive, and from there it’s not a huge jump to the explanation they found.
