There Was Ft. Hood I and Now There Is Ft. Hood II, and There Was Also an Attempt To Blow Up A Restaurant Near Ft. Hood Which Was Frequented By U.S. Soldiers

From commenter, Aldo:

Still waiting for the definitive Islam link that seems fairly probable. Some interesting things I've come up with so far though - I used google maps to work out that Lopez lived exactly 3.8 miles - 8 minutes drive from the only mosque in Killeen Tx. Yes the mosque Nidal Hassan visited... 

Also rediscovered the 2011 news about the foiled plot to blow up the restaurant near Fort Hood frequented by soldiers from the base. Thought I'd mention this because many who are reporting this shooting keep referencing the Nidal Hassan shooting as though that were the only past incident regarding Fort Hood that's worth mentioning.
