LAS VEGAS - Daisy Gomez remembers May 9, 2002 as a day that will forever be scarred in her heart. That was the day a tragic car crash claimed the lives of two teens.

The 16-year-old driver, Ashley Troester, was speeding on her way back to Las Vegas High School. Troester and four passengers were returning from a quick lunch at Burger King. She hit the gas but lost control, crashing into a pole and splitting her car in half. The wreck killed her and 17-year-old passenger Natasha Keeter.

"In an instant, everything was gone. Everyone's life changed," Gomez said.

She was Natasha's friend. Now a parent, Gomez says she's a responsible driver because of those tough, agonizing lessons first learned when she was a high school senior.

Metro Police are planning a Sobriety Checkpoint in the northeast part of the Las Vegas valley for Saturday.

The checkpoint will be at Charleston Boulevard and Arlington Street from 7 p.m. to 3 a.m. Police will be looking for people driving under the influence. There will be a special emphasis on drivers who have been using drugs. Drug Recognition Expert Officers will be on hand to evaluate drivers.

The department chose this intersection after it looked at the number of crashes or violations related to drugs or alcohol in the Northeast Area Command. Metro found in the last 90 days there were 67 crashes and 12 alcohol or drug related incidents along the area of Charleston where the checkpoint will take place.

The checkpoint is being paid for by a Joining Forces Grant from the Nevada Department of Public Safety Office of Traffic Safety. The money will also be used to fund deployment of a DUI van and phlebotomist.
