Michael Anderson — who became known as the Craigslist killer after he lured a 24-year-old woman to her death by posting an ad for a babysitter — will spend the rest of his life behind bars. And, no, the 20-year-old will not be receiving parole.

Katherine Olson’s heartsick family was in tears when the judge sentenced the young man — who killed Olson and disposed of her body in the trunk of her own car. The tragedy happened 17 months ago in Minneapolis, but her death made a long-lasting impact globally by raising awareness of the often-anonymous Internet’s dangers.

According to reports, Olson arrived at Anderson’s home in response to an ad she found on the website Craigslist.org, which operates largely on classifieds. When she tried to leave, he pulled out his father’s gun and shot her.

The victim’s father, a Lutheran pastor, and mother, Nancy Olson, were in tears in the courtroom. Her father, Rev. Rolf Olson, told ABC News in 2007 that Katherine was "larger than life" and, "unfortunately, too trusting."

"She had found benefits on Craigslist," he said, "but in her trusting nature, she fell into this trap."
