Breaking Benoit News: Big Argument Before Killings?

In the July 10th issue of the Wrestling Observer, Dave Meltzer reports further details of the Benoit family tragedy:

The Police Department believes (but are not absolutely certain) that the argument between Nancy and Chris Benoit that resulted in Nancy Benoit's murder was the result of Nancy telling Chris she was leaving him.

Apparently Benoit actually spoke to next door neighbor Holly Mcf-gue sometime on Saturday, after the killing of Nancy Benoit, but before the killing of Daniel Benoit.

Benoit gave neighbor Mcf-gue a cover story of how sick Nancy and Daniel Benoit were (the same story that was reported in the phone calls to WWE workers). This was again after the killing of Nancy Benoit, but before the killing of Daniel Benoit. Mcf-gue has previously been reported by many sources as the person who actually led police into the Benoit property and first discovered the bodies of all three Benoit's. She came out of the house screaming.
