so I just found this bit as well -
[Abductions by strangers are rare in Canada, but Neufeld says every year the WPS get 15 to 20 calls of children being abducted by a parent. Case in point: this week’s snatching of two children, 11-year-old Montana Giesbrecht, and her nine-year-old brother, Josh. Police believe they may be with their mother, Sandra Giesbrecht, who, as of Wednesday, is wanted on a Canada-wide arrest warrant.
"We haven’t had an AMBER Alert since I’ve been in this department," Neufeld said. "We have to have concern of grievous or bodily harm to send one out."
Neufeld says if a family is able to rally people to help search for a missing person, the police have no control over them. She says police also have no control on whether or not the case is featured prominently in the media.
"We do the same with everyone... we do ground searches, but when we do it it’s evidence-based or where we think a person will be," she said.
"The hardest thing for a family is to wait and not know. You feel compelled to just do something."
Neufeld says it’s why when a body is found — or recently when a boot and a portion of a body was found in the Red River near Selkirk — they contact families of long-term missing people to let them know when it is not their loved one. And they also call the family of the person they believe the body to be to let them know DNA testing is being done.]
