A security camera at a gas station on the northeast side of Indianapolis shows Rickhof buying gas for her black SUV about 2 a.m. Thursday. A friend says Rickhof stormed out of his home about an hour later.
Police say she may be disoriented and require medical assistance.
Rickhof is 5 feet 8 inches tall, 140 lbs, with blond hair and blue eyes. She was last seen wearing a pink tank top and black yoga pants.
