    Even though the authorities assumed that the trio of escapees drowned as they set off into the sea on a makeshift raft, it seems that at least two of them managed to reach land safely and find refuge abroad.

    It appears that a decades-old mystery related to a daring escape from one of the most infamous prisons in the United States has finally been unraveled via the creative application of facial recognition technology, Campaign magazine reports.

    The escape in question took place in 1962, when three inmates – Frank Morris and the Anglin brothers, John and Clarence – managed to slip out of their cells and get off the island via a makeshift raft. Their subsequent fate has since been unknown, though the authorities eventually assumed that the escapees drowned.

    According to the media outlet, an Irish creative agency called Rothco banded together with AI experts from Identv in order to determine whether two men in a photograph which emerged in 2015 and which allegedly depicts the Anglin brothers living in Brazil in 1975, are indeed the same as those who escaped from prison.

    ​As Mark Hughes, chief AI scientist at Identv, explained, the neural network-based system they employed in order to accomplish this task, was "trained" via a special algorithm to differentiate between people's faces.

    "Once we have a model trained, it provides us with the ability to generate a mathematical fingerprint describing in detail the visual aspects of somebody’s face. These facial fingerprints are highly discriminative", he said. "We can then compare this facial fingerprint to other fingerprints we have in a database to generate a match, similar to how today’s police fingerprint matching system works. Identv has developed techniques to carry out this matching process in tens of milliseconds over millions of faces."

    Alan Kelly, chief creative officer at Rothco, also remarked that "The Long Shot", as this joint campaign is called, is a "novel example" of implementing contemporary digital tools and creative knowledge to extract "newfound stories and opportunities" from a "hidden piece of the past".

    "Technology is advancing at such a rate, it can leave you a little dizzy and, short of obtaining DNA proof, there will always be a little room for mystery. But as far as technology is concerned – the prisoners made it", he noted.
