Windsor's search for the people in the photo went viral Tuesday after she shared it on Twitter. "I almost went up to the dad and asked if he wanted it. Now I wish I had," Windsor tweeted Monday night alongside the photo. "Twitter if you have any magic, help him find this."

Now, Windsor has confirmed that she's been in touch with the father in the photo through Twitter, though he has asked to remain anonymous. "The search is over!" she tweeted Thursday. "The photo has reached the dad and family."

The iconic spire at the top of the cathedral and a large section of the roof collapsed in the fire that broke out Monday. A French judicial police official told the Associated Press on Thursday that investigators think an electrical short-circuit most likely caused the fire, although the investigation continues.

French President Emmanuel Macron has vowed to rebuild the landmark. Fire officials warned that the more than 800-year-old cathedral structure remains very fragile and extremely dangerous for construction workers and others.
