Serious allegations today about UFC star Conor McGregor. On the same night he made headlines for this stunt - punching out a mascot at the NBA finals, a woman says McGregor violently sexually assaulted her in a bathroom at the arena. Now as Les Trent reports, McGregor’s reps are denying the allegation. And, it's happened again. American tourists dead after being found unresponsive at a luxury hotel in Mexico. And once again, authorities suspect they may have died from inhaling carbon monoxide. Jim Moret has more, including what you can do to stay safe. Plus, now an incredible story of bravery and good fortune. A mother and her daughter were hiking when the mom fell down a steep incline. Her daughter caught her with one arm…her only arm, for what seemed like forever. She kept her mom from slipping away until as luck would have, another hiker came along. And, it's a message from some heartbroken parents - talk to your teenagers. Tell them whatever happens now isn’t forever. Their son, a popular high school athlete, took his own life after getting snagged in a sextortion plot.
