This could well be a phony "suicide." It has, at least at this early juncture, some of the same strangeness as the death of Vince Foster.
If it proves out to be a real suicide, since the victim was a football player, you can bet that it will be thought of by the MSM as a being caused by multiple concussions that went unrecognized by the football staff and athletic department. Don't be surprised if the MSM plays up the "concussion" line even as it obfuscates the true cause of death.
We are talking about a guy that was 6-4 and over 300 lbs. If somebody killed him and then stuffed his body in a dumpster, I presume it would have to be at least two somebodies.
I would expect forensics to clear that up. Is there gunpowder on the player’s hand to prove he fired a gun? Is the bullet angle consistent with a self-inflicted wound? Are there fingerprints of others on the gun or the player’s clothes?
