Sadie Grosso (Earth-90: Pre-Crisis)

"The Flash did it! I've seen it with my own eyes!"

- Sadie Grosso's statement to the police

Sadie Grosso was a Central City resident that witnessed all fires caused by Noble John Spanier.

The Fires
In 1990, Sadie has already two mysterious fires at the river front and during the third one he encountered Fosnight who was talking to her while pick pocketing someone. The next day, Barry Allen and Julio Mendez came to interrogate her about anything she may have witnessed. Days later, the Flash would tie the arsonist responsible for the fires to a pole, and she witnessed him and gave her statement to the police despite officer Murphy not believing her.
