Don't know about the gross part (seems relevant, exactly how they pursued the suspect). However, kind of amazed you're the only reference on here.

The part of the UnitedHealthCare situation that seemed kind of amazing from a personal perspective was how little the suspect actually seemed to look like the public photos released.

If I were calculating "confidence", that would have been relatively far down in the percentages. Vaguely similar to a lot of euro-background ethnicity faces. Maybe there were other photos the police had and didn't release. However, from what was available, with two photos showing the mask removed and one with somebody smiling, not a great match.

Tried four reverse images searches online. Started with 1920x1280 release (blurry), and got down to two (2) ~550x550 images of the cropped face. Results from four attempts were:

  1) Complained about quality, gave back electro-music looking guy in rainjacket
  2) Not a valid face on both photos
  3) Gave back police publicity photos as only results
  4) Not a valid face on both photos

Not a great sensation of positive confidence percentage on the actual match. Figure the police likely would have attempted to release a relatively high quality still image to help crime solvers.
