The Saskatoon Police Service is asking the public for any video or dash cam footage that may help in the search for missing Dawn Walker and her son.

Walker and her 7-year-old son Vincent Jansen were last seen this past Friday.  Her truck was eventually found at Chief Whitecap Park with a few personal belongings discovered in the area.

Police are now seeking any dash cam footage or relevant surveillance video of the Chief Whitecap Park area this past Friday evening.

Anyone with possible video surveillance that may be helpful in the investigation is asked to get in contact with police.

In the meantime, Police continue to search the area using airplanes, underwater rescue crews, and several other resources looking for Dawn and Vincent.

While authorities have not yet found any evidence of foul play in their disappearance, they are not ruling out any possibility.

Walker is the current CEO of the Federation of Sovereign Indigenous Nations.

On Tuesday, Heather Bear, Vice-Chief of the FSIN, implored law enforcement officers to investigate any leads in the disappearances.
