Multiple people died during an obscurus attack on New York City in the movie, Fantastic Beasts and Where to Find Them.
The deaths include
senator Henry Shaw Jr., Mary Lou Barebone, and perhaps others.
Given that one of them was famous, how did the aurors explain their deaths when they cleaned up New York City and wiped the memories of muggles at the end of the movie?
We know magi can't bring people back from the dead, so those deaths can't be restored to normal when the aurors restored everything else to normal.
