I read somewhere that this person saw an episode that the culprit painted the ceiling with a type of poison/substance and people would get killed after inhaling the toxic air. I tried searching for that episode but can’t seem to find it. Does that episode really exist?

Someone please help. I read somewhere that a person previously saw an episode of Detective Conan where the ceiling was painting with a substance(?) that would make people inhale it as poison. I can’t seem to find that episode and I don’t have any memory of watching that ep. Please. My mind won’t be at ease if I can’t find it.
