There exists an online tool here http://www.pictriev.com/fc.php to measure/evaluate the similarity between faces.
From the existing pictures of “Katie Foley” and “Alex Israel” I cropped an image of their respective faces and uploaded them to their measurement tool.
Both of the pictures I cropped are attached to this message as Foley.jpg and Lanza.jpg. The picture from where I cropped them is also attached as Foley_Lanza.jpg
Then I fed them to the evaluation tool at the site mentioned above, and you can see screenshots of the results below.
Similarity meter: 88%.
Then, if you click on “Identity” it says:
These facial images are:
from the same person
Of course if you look around on the web, the first thing Google and others bring up is claims of having “debunked” that they are the same person.
You are encouraged to reproduce the simple experiment I’ve just described (you can use the 2 jpg files attached to this message or crop your own from the existing pics), to confirm that your eyes agree with this tool and this tool with your eyes.
