What type of art style do you use? You could try searching for zombies in the market because they tend to come with some dead looking bodies and are usually more modern looking. Not quite Sci-Fi, but a bit further from typical medieval fantasy. If you are into the hand-drawn style, this set contains some bodies: <a href="https://marketplace.roll20.net/browse/set/715/" rel="nofollow">https://marketplace.roll20.net/browse/set/715/</a> and this one has some bodies too: <a href="https://marketplace.roll20.net/browse/set/1192/" rel="nofollow">https://marketplace.roll20.net/browse/set/1192/</a> If you prefer 3D renders, Sunset Industries ( <a href="https://marketplace.roll20.net/browse/publisher/158/" rel="nofollow">https://marketplace.roll20.net/browse/publisher/158/</a> ) puts different poses for each token character and a few of them come off as dead and they're Cyberpunk which can be Sci-Fi-Ish: <a href="https://marketplace.roll20.net/browse/set/3176/" rel="nofollow">https://marketplace.roll20.net/browse/set/3176/</a> <a href="https://marketplace.roll20.net/browse/set/3178/" rel="nofollow">https://marketplace.roll20.net/browse/set/3178/</a> I hope that helps!
