HARRISVILLE -- Brandi Lee Stilke, 26, has "Aubrie" tattooed on her left foot. It's the first name of her 3-year-old daughter, Aubrie Joe Anderson.
A jail officer made note of it as Stilke turned herself in Friday evening after being arrested for the accident that killed Aubrie two months ago.
"On a case like this, the investigation sometimes runs slow," Harrisville Police Chief Max Jackson said, noting that Stilke's case file, full of reports and test results, is 5 inches thick.
"Some people are eager to see results in a case. I'm sure the clock runs slow for them, but we have to approach it with an organized and careful manner."
Stilke, of Plain City, was driving north on U.S. 89 when she veered right onto a sidewalk and into a vacant lot around 2:30 p.m. Feb. 23. The car continued toward a parking lot at 1140 North and hit decorative boulders.
Aubrie was riding in a car seat at the time but was injured. She was flown to a Salt Lake City hospital in extremely critical condition and died just after 2 a.m.
Stilke was treated for a fractured hip at McKay-Dee Hospital in Ogden. She told police in February that she blacked out before the accident.
Investigators determined she had OxyContin and marijuana in her system at the time of the accident, Jackson said. Police found in her car OxyContin and Lidoderm patches, painkillers for which she did not have valid prescriptions, he said.
Once the investigation concluded Wednesday, the Weber County Attorney's Office advised Stilke's attorney, Roy Cole, that she should turn herself in to Weber County Jail, Jackson said.
She arrived Friday evening and surrendered to a Harrisville police detective.
Stilke was booked for driving with a detectable controlled substance that resulted in a death, a second-degree felony, illegal possession of a controlled substance, a third-degree felony, and having an open container of alcohol in the car, a class C misdemeanor.
The official charges are expected to be filed Monday in 2nd District Court. Stilke could face up to 20 years in prison if a court convicts her on the felony counts.
