SACO, MAINE- Police are trying to find a motive for the knife attack on a mother of five at a grocery store by a woman who didn't know her.

Wendy Boudreau was stabbed and later died at a hospital on Wednesday. It was near the ice cream freezer.

Conner MacCalister is charged with murder and police say she lived in an apartment complex not far from Boudreau's house but there is no indication they knew each other.

Neighbors describe Boudreau and her family as beloved members of the community and a friend says Wendy Boudreau was the "glue of the family."

MacCallister is expected to make her first court appearance on Friday.
