A woman was sentenced to more than 10 years behind bars Friday after she admitted to driving under the influence of Xanax in 2008 and hitting a car driven by Megan Marty, 16, killing her.

But even before the sentencing, it was an emotional afternoon for the victim's family, the defense's family and the defendant - 24-year-old Kristin Spires, of Hawthorne.

"I take full responsibility for what happened in Megan's death," Spires said. "I think about Megan every day, every moment, every second."

Something Megan's mother, Linda Ford, made clear she does too in remarks directed at Spires.

"Missing her is what I get to do for the rest of my life," Spires said. "And, it was 100% preventable."

Spires was sentenced to 124.5 months in prison.

The charge of DUI manslaughter carries a mandatory minimum of four years in prison. Spires got more than double that.
