Expert Response
Without seeing images of what you observed it is impossible to determine the problem. The only thing I can think of without more information and images is an insect ate your plants. Caterpillars can leave behind frass (insect excrement) while they feed that can be small black specks. Other than that, we would need more information to determine the cause of your zinnias dying.
