Hernandez is a psychopath, imho. His demeanor at the arraignment appeared to be intentionally intimidating and thuggish. It seems that he was not well-liked by the Patriot’s organization or by his fellow teammates.
I generally don’t follow high profile homicide cases, but judging from what is known, and other evidence, like a .45 shell casing recovered from a rental car matching the Lloyd murder scene, Hernandez is toast. And killing to silence a witness in another homicide is needle material, if Massachusettes has the death penalty.
