Now, Quebec provincial police are looking for the public's help in uncovering the circumstances surrounding her disappearance.

On Thursday morning — the 15th anniversary of her disappearance — investigators with the Sûreté du Québec set up a command post on Guillaume-Couture Boulevard in St-Romuald, across the river from Quebec City.

Godbout's father, Jean-Guy Godbout, met with reporters at the post.

He said this time of year has been "hell" ever since his daughter went missing — he said he thinks of nothing but his missing daughter for the entire month between her birthday on Aug. 26 and the anniversary of her disappearance.

Godbout, a mother of two, left her home in St-Romuald around 11:30 p.m. on Sept. 23, 2000. She was wearing a black nylon coat, white leggings and was wearing a number of rings on her fingers.

Investigators believe she left her home the night before following an argument with her partner. Godbout did not take any personal belongings or identification when she left.

She has green eyes and her hair was red at the time of her disappearance. She also has a butterfly tattoo above her left breast and a tattoo of a black panther with flames on her right shoulder.

SQ investigators are looking to speak with people from the area at the time who may have seen or heard something that could help investigators solve this cold case. They are asking that anyone with tips go to the command post or call 1-800-659-4264.​
