COEUR d'ALENE - Rathdrum resident Don Graham died on the job on Dec. 15, 2010, while driving a company car on Interstate 90 back to his office in Post Falls. A simple, everyday act, with a swift and violent end.

Now a 34-year-old Shoshone County woman, Lisa M. Calbick, is facing up to 10 years in prison, following a jury trial in 1st District Court that concluded Friday and ended in a conviction for vehicular manslaughter with gross negligence.

Graham's wife, Keren Graham, said, "My hope is that no one ever has to face such a traumatic death as he did - hit from behind by a wild, weaving driver, who caused him to hit a sign and roll three times to his death."

Don Graham was eastbound about 3:30 p.m. that day, traveling about 70 miles per hour, when Calbick, who also was eastbound, rear-ended him just east of the Washington-Idaho state line.

Witnesses said she was speeding at 85 to 90 miles per hour and darting in and out of lanes just before the crash.

When she struck him, Graham lost control and his car flipped. He was pronounced dead at Kootenai Medical Center.

Graham was a 77-year-old U.S. Air Force veteran, and had been married 29 years.

"I know justice comes slowly, if it comes at all nowadays," Keren Graham said. She feels like the jury's verdict provides a measure of justice.

Calbick is out of custody, and she is scheduled to be sentenced Oct. 1.

Graham said, "I hope that the sentence for Ms. Calbick will be appropriate and will not be amended to a lesser one out of the light of day."

She also said she hopes nobody has to witness such a death again, or be the wife or son left behind, who suffer their own trauma and who will never be the same again. His son was 12 years old at the time, now 14.

During the trial, the defense claimed Calbick was hit by a mystery third car, and that propelled her into Graham's car. The defense and prosecution both called accident-reconstruction experts.

"It's good to get some closure after a year and a half," said Kootenai County deputy prosecutor Art Verharen, who handled the case for the state.
