Jasmine Olleik was last seen Wednesday at about 3 p.m. while walking with a woman and getting into a four-door blue sedan in the 1500 block of Blohm Drive in Ottawa's south end.

Olleik was wearing a pink winter jacket and pink and brown boots that day, according to police.

Her father, who has full custody, reported her missing later that day. He told police he believed the mother, 42-year-old Nina Grebenschikov, had likely taken the girl.

Olleik is described as a white girl standing five feet one inches tall with a slim build, short, dark brown hair and brown eyes.

The mother is a white woman, standing about five feet seven inches tall and weighing about 125 pounds. She has auburn hair and hazel eyes, but she might have recently dyed her hair blonde, police said.

Anyone with information is asked to contact Ottawa police at 613-236-1222, ext 5407 or Crime Stoppers at 613-233-8477.
