LAS VEGAS -- A chilling account of what happened Saturday afternoon at a Summerlin Costco has surfaced, blasting Las Vegas police for what witnesses call excessive force.

Erik Scott was shot and killed by police. Metro says he was armed and posed a threat, but witnesses are coming forward saying they don't believe that's true.

At least one of these accounts was from a couple who says they were just feet away from where Scott was shot. They says he didn't draw his gun or point it at police, but officers shot anyway.

Scott's cousin and family friends say witnesses are reaching out to them.

LAS VEGAS -- A shooting at a Costco in Summerlin is raising questions about concealed weapons permits.

Erik Scott was gunned down when police say he refused to drop a weapon he had on him. But Scott's friends and family say he had a concealed weapons permit and was knowledgeable with the laws.

Private property like shopping malls, or even the Costco where the shooting happened, can prohibit weapons from being on property without any signage. Even if you have concealed weapons permit, private property owners can prohibit weapons.

"The line we always use in class, 'When you say the magic word gun, make sure your hands are visible and wait for the officer to tell you what to do,'" said The Gun Store owner Bob Irwin.

It's a line that could mean the difference between life and death. Irwin has released a book on the guidelines for carrying concealed fire arms in Nevada.

LAS VEGAS -- In a matter of minutes, car thieves can break in, steal and strip your vehicle, selling its parts for thousands on the black market. Experts want to show how they do it, because Las Vegas drivers are some of the most vulnerable in the country.

Experts say while valley theft numbers have gone down the last few years, common sense and a few simple steps will help put the brakes on this bad problem.

A three-man mock thief team gets their game plan together, preparing to dismantle a 2007 Toyota Camry down to the frame. Now you see it, now you don't.

"It's an eye opener to see just how quickly a car can be stolen and stripped of it's parts," said Metro Auto Theft Sgt. Andrew Patzer.
