I can't fault MSM for not covering a third-anniversary vigil of a murder.
I agree with you. However, it looks as if this story was never of real interest to the MSM. That's the point.
I used Nexis to run a comparison of print media coverage of the Shepard and Stachowicz murders. I searched for media stories on "Mary Stachowicz" between the day of her murder, Nov. 13, 2002, and today. There were 25 items. (Nexis also includes press releases and letters-to-the-editor.)
I then did a search for "Matthew Shepard" for the same time period. The Nexis search engine produced this notice: "This search has been interrupted because it will return more than 1,000 documents."
Apparently, they didn't cover the crime very much when it happened, either. This is clearly a "dog bites man" story that, in a saner time, would have been widely picked up. I think the comparison between this story's coverage and that of Matthew Shepherd is very, very telling, indeed.
