Mystery surrounding 3 Kansas City Chiefs fans found dead outside man's home leads to accusations from victim's family

It has been three weeks since three Kansas City fans joined friends to watch the Chiefs play the Los Angeles Chargers in the final game of the regular season. Two days later, their bodies were found in the backyard of the home of their friend Jordan Willis.

While Willis has denied any knowledge about his friends' deaths, one of the victims' brothers told CBS News that "he's not telling the truth."

Police still haven't said how the men died, but affirmed this weekend amid intense public speculation that they still have no evidence of foul play.
