Authorities say Michael Anderson lured Katherine Ann Olson to his family's split-level house in Savage, somehow got her upstairs to his bedroom, where he shot her in the back with a .357 handgun, dragged her downstairs and tied her ankles in red twine.
Despite an uneasy feeling in her gut about the person she was about to meet, Katherine Ann Olson showed up for her new baby-sitting job at a dilapidated house in Savage.
She was there to watch a child between 10:30 a.m. and 5 p.m. Thursday after being hired by "Amy" through an ad posted on the popular Craigslist website. Before heading out, she mentioned to her roommate that her new employer "seemed kind of strange."
She placed her last cell phone call to Amy's phone just before 9 a.m. A short time later, authorities say, she was met at the house by 19-year-old Michael John Anderson, a paintball fanatic who dropped out of an alternative high school and was shy around women.
Authorities say Anderson lured Olson, 24, to his family's split-level house, somehow got her upstairs to his bedroom, where he shot her in the back with a .357 handgun, dragged her downstairs and tied her ankles in red twine.
The new details in the Craigslist killing emerged Tuesday as Anderson was charged in Scott County District Court with second-degree intentional murder. At one point, he told police that another person had killed her and that a friend "thought it would be funny."
Authorities, however, say that evidence points to Anderson acting alone.
They say he stuffed Olson's body in a sleeping bag in her trunk and drove five blocks away before ditching the car at Kraemer Nature Preserve in Burnsville.
He wrapped her crushed cell phone in a blood-smeared towel -- that had his name written on it with a black marker -- and stuffed it in nearby trash can, authorities said.
His motive bewildered authorities and Anderson's friends. After first denying the cell phone contact with Olson, Anderson later told police he witnessed another person kill her.
A friend "thought it would be funny," he told police, according to the complaint.
Authorities said there was no sign of a sexual assault. They found the handgun and a shell casing in his blood-spattered bedroom. A trail of Olson's blood showed her body had been dragged down the stairs. The steps had been cleaned but not the risers, according to authorities, who declined to speculate on a motive.
"The only person who knows that right now is the defendant," Scott County Attorney Patrick Ciliberto said. "There is certainly no sense in her death. She was a talented, bright young woman and her life is gone and there's no explanation for it."
At Olson's visitation on Tuesday at Richfield Lutheran Church, her mother, Nancy Olson, flashed a bright smile as she stood by her daughter's casket and watched a video of her daughter portraying Maria in a church community theater's production of "The Sound of Music."
Neither of Olson's parents talked about the case Tuesday, choosing instead to celebrate their daughter's life as shown through dozens of photographs. Funeral services will be held at 2 p.m. today in Edina for Olson, a St. Olaf College graduate whose family described her as "a joy."
In an earlier e-mailed statement, her father, the Rev. Rolf Olson, a pastor at Richfield Lutheran Church, said that Katherine "believed in the essential goodness of humanity, sometimes naively so."
On Facebook.com, a social networking site, more than 1,200 people had signed up to pay respects.
Bail set at $1 million
Anderson, handcuffed and gazing blankly from beneath black bangs, was held on $1 million bail. He could face first-degree murder charges once a grand jury is convened.
