Even more disturbing details are emerging in the grisly Stephanie Moseley/ Earl Hayes murder-suicide case.

As we previously reported, rapper Earl Hayes shot and killed his wife, VH1 star Stephanie Moseley, in an L.A. apartment yesterday (Dec. 8), turning the gun on himself and ending his own life as well. TMZ is now reporting that Hayes was FaceTiming his good friend, boxing champion Floyd Mayweather, Jr., when "he flew into a rage" and killed Stephanie and himself. Mayweather reportedly witnessed the unimaginable horror.

TMZ also reports that Hayes became enraged when accusing Moseley of past affairs, including a supposed tryst with Trey Songz. Sources told the site that Hayes separated from his wife about two years ago after her alleged affair with the singer. He ultimately reconciled with his wife, though sources claim he never got over the alleged affair and frequently brought it up.

Songz took to Twitter to express his sadness at the passing of Moseley, tweeting:

In addition to starring on the Vh1 show 'Hit the Floor,' Moseley was also a successful backup dancer for huge artists like Chris Brown, Britney Spears and Usher.

Our thoughts are with the family and friends of the victims.
