Jenny Price appears to be an LA based writer. I found this list of articles where she is credited with writing an anti-gun article in 1998, apparently two years before this alleged tragedy;

Hmmmm.
Jennys article doesnt pass the smell test.
You dont suppose she would make it up do ya?
There is a Jenny Price reporter who has written a lot of articles in Wisconsin, most involving shootings, etc. If this is the same Jenny Price writing gun control articles in 1998, the chances are that her story was fabricated.
A search of the Los Angeles Times archives for murder + david + fiance reveals nothing. Nor does "David Price".
