A driver who was under the influence of marijuana was sentenced to three years in prison for criminally negligent homicide in the death of a 53-year-old woman killed on the Seward Highway.

Timothy Wood, 33, was behind the wheel when his Chevy Blazer crossed the center line and slammed into a car driven by Diane Bahnson of Girdwood in 2005.

Wood's blood tested positive for marijuana.

Troopers said Wood was driving erratically before the accident.

Wood was originally charged with second-degree murder, but technical problems with the blood test evidence made it hard to take the case to trial, according to prosecutors. In a plea agreement, the charge was reduced to criminally-negligent homicide.

Bahnson's parents and husband came to Wood's sentencing hearing. They urged Superior Court Judge Philip Volland to give the stiffest sentence possible under the agreement.

"I believe Mr. Wood has gotten away with murder," Bahnson's husband, Reid, told the judge. "He destroyed not only one life, but many."

Wood apologized to the family. He said not a day goes by that he does not think about what he has done.

Volland told the family that the sentence was in line with recent sentences for similar crimes.

Wood has already served the time awaiting his sentencing hearing. He also will lose his license for five years.
