I'm way late in getting to this, but I wanted to post it anyway, especially since the actual details of Rebecca Clements' muder are so different than what I first made up on reading the early enigmatic account, which included the erroneous report that Clements was pregnant.

Clements, who was gunned down in cold blood as she waited tables in the Hominy, OK, Diner, was apparently murdered because of a real-estate dispute and a letter-to the-editor in the local newspaper. The man charged with her murder, Roy Westbrook, rented a house to Clements' sister and was having some disupte with his tenant.

Editor & Publisher talked to Ramona Brown, the general manager of the local newspaper, and got the story:

According to Brown, Westbrook spray-painted the phrase "get out" on a house rented by Clements' sister, who apparently owed Westbrook money. This prompted Clements to write the letter to the editor, which criticized prominent citizens for vandalism but did not mention Westbrook's name.

Once the letter was published, Westbrook, a prominent local citizen, appparently figured his best move was to head a pawn shop and buy a Glock. The full E&P story is here.
