There's been another apparent assassination of a police officer, this one coming in New York City. The victim was a Myosotis Familia, a mother of two, who was reportedly quite popular on the force:
The murderer was Alexander Bonds, out on parole from a 2013 robbery, who had assaulted another police officer with brass knuckles in 2001:
It's been my recent vague impression that a disproportionate number of men who've committed violent crimes have had a vestigial sagittal crest, i.e., the top of their skull seems to come to almost a peak.
Bonds, who had expressed his hatred of the police in a recent Facebook post, has the wide, powerful jaws one associates with sagittal crests (the original purpose of which was to anchor the jaw muscles to make for a more powerful bite).
Here's are a few more examples, and another.
Bonds doesn't have as powerful a build as some of the others with sagittal crests, but he was apparently homeless from time to time, which may partially explain that.
