Who is Constable Ned Cameron from Mrs. Mike the Story of Katherine Mary Flannigan and what is their importance?

Constable Ned Cameron is the policeman in Grouard, who tries to rescue Jerry West, Timmy's hunting buddy when a grizzly attacks and kills Jerry. Constable Ned is not as capable as Mike in his job, and he is a source of irritation to the group who walks to the Mission because he cannot cease talking about the grizzly bear attack, much to the dismay of Timmy Beauclaire.
