Investigators are continuing to look into the events that lead up to the shooting at Fort Hood on Wednesday that left three people and the gunman dead and 16 others wounded.

FOX News Radio's Eben Brown reports from Killeen, Texas:

Investigators here are trying to piece together the pre-shooting events-- including that verbal altercation. Lieutenant General Mark Milley:

Milley: "It's a strong possibility that that, in fact, immediately preceded the shooting. But we do not have that definitively at this point."

But now, a Facebook posting has been discovered, according to FOX News Latino, in which Specialist Ivan Lopez says he's 'full of hatred' and that 'the devil will take him'. He talks about being robbed. This post is from March 1st, the same day he bought the firearm he used in the shooting.
