A medical examiner has confirmed that the remains found near Cochrane, Alta., on Saturday morning are human.
Children playing just south of town came across what locals describe as a human skull.
The RCMP's major crimes unit is investigating.
"The investigation is still in its infancy and at this point we do not have any more information or details to release other than that the medical examiner's office has confirmed that the remains are human," said RCMP in a release.
RCMP plan to update the public when the investigation has progressed.
