LAS VEGAS -- An arrest warrant has been issued for boxer Floyd Mayweather, Jr. He has been charged with battery after poking a security guard in the face last month.

In a police report, the Southern Highlands security officer was confronted by Mayweather after putting a parking violation ticket on his vehicle. The boxer then allegedly slapped the ticket onto the security officer's vehicle and began poking him in the face.

Mayweather already faces battery charges for another incident where he is accused of attacking his ex-girlfriend and threatening his sons. He is due in court to face those charges next month.

LAS VEGAS -- The Clark County Coroner has released the name of the man gunned down in front of his house on Wednesday night.

The coroner says 28-year-old Nathan Paet was killed by multiple gunshot wounds. Paet was in the Air Force and stationed in at Nellis Air Force Base, a member of the 757th Aircraft Maintained Squadron. He had just opened his garage door when shots rang out.

At around 11:30 p.m. Wednesday night, neighbors near Alta Monte Court woke up to the sound of gunfire ripping through the Mountain's Edge neighborhood.

Early Thursday evening, homicide investigators and Air Force personnel returned to the garage where they say the victim was shot multiple times while trying to leave for work. The wounded man managed to get into the home, where he collapsed. He was rushed to the hospital and later died.

Witnesses say after the shooting, they saw a man wearing a tan or brown-hooded sweatshirt heading east.

RED ROCK CANYON, Nev. -- The vandalism that may have destroyed ancient artwork carved into the stones at Red Rock Canyon could cost thousands of dollars to repair, if experts can even do it.

The rock is in a remote area that was challenging hike to near Willow Springs and the Red Rock Loop Road. Experts say the pictographs that remained on the canyon walls for 1,000 years were destroyed in seconds by spray paint.

"It's not simply a question of using some kind of solvent and washing it off. It's like treating the Sistine Chapel. You might be able to remove the damage, the spray paint, but you still want to retain the pictographs underneath," said BLM archeologist Mark Boatwright.
