Moncton, N.B. -
The family of Donna O'Rielly is rejecting the possibility that the missing New Brunswick woman has run off.
Investigators admit they are no closer to knowing what happened to the 54-year-old Moncton woman than they were three weeks ago when she disappeared.
Police are considering all options in the case - including the possibility that O'Rielly left of her own accord and doesn't want to be found.
Karen Streek insists her mother wouldn't put the family through something like that.
"We know that that's not the case," Streek said Friday. "We know for sure that mom's not just sitting out there, hiding out somewhere on her own accord.
"So it is definitely disappointing and frustrating for us. But, at the same time, we do understand why the police do it."
Police say if O'Rielly did willingly leave, then she has done nothing wrong and she can call them so the family can be told she's OK.
The woman was last seen leaving her job at a Moncton-area shopping mall on Feb. 26.
She was clutching her car keys in her right hand, but her car was found sitting in the parking lot.
Police say they have received more than 600 tips in the case.
