The actress, 24, has been "extremely cooperative" since entering the Century Regional Detention Facility in Lynwood, Calif. Tuesday morning, Whitmore said earlier.
Lohan, who smirks in her mug shot, will spend her days in solitary confinement in a 12-foot-by-8-foot cell.

"She will be kept away from general population," Whitmore said.
After Lohan surrendered, her attorney Shawn Chapman Holley told reporters that Lohan "is asking for your prayers and support. She has stepped up and accepted responsibility."

Holley described Lohan as "a talented young woman and I appreciate that she has accepted responsibility here. She is scared -- as anyone would be -- but is as resolute as anyone could be and she is doing it."
