HENDERSON, Nev. -- John Dlouhy has a drink at Henderson's T-Bird Lounge. He's doing so under the watchful eye of police officers.

Dlouhy volunteered to show the effects of alcohol on one's driving ability for one main reason -- he lost his mom and dad in a car accident 29 years ago.

Four vodka cocktails later and Dlouhy took the wheel of the simulator, having difficulty staying on the road. One of the tell-tale signs in the simulator is weaving across the double yellow lines and also not knowing what speed you're going.

Dlouhy handed over the keys to Designated Drivers, a group that has found it difficult to keep their program alive in these tough times.

LAS VEGAS -- One year ago, Steven Koecher pulled his car into a Sun City Anthem neighborhood and walked away. He has not been seen or heard from since.

Koecher, a devout member of the Church of Jesus Christ of Latter Day Saints, came to Las Vegas from his St. George, Utah home on Sunday, December 13, 2009, unannounced to friends and family. His car was found abandoned days later, parked on a dead end street deep in the heart of southern Nevada suburbia. The last known images of Koecher were captured on a neighbor's home-surveillance camera. He is seen walking down a neighborhood sidewalk, crossing the street, and disappearing out of frame.
