Aunt Pleads For Missing Idaho Kids

After nearly a week of searching for clues, detectives and forensics experts are making a final searching of the Groene house before boarding it up for good.

While the triple murder investigation continues, authorities and family members are still hopeful they'll find 8-year-old Shasta Groene and her 9-year-old brother Dylan Groene.

The two have been missing since the bodies of their brother, mother, and their mother's boyfriend were found in their home almost a week ago.

Wendy Price, the missing children's aunt, urged them to "Hang in there, we'll find you, you know your brother is watching over you."

The coast guard auxiliary has been conducting shore searches around lake Coeur d'Alene as part of the effort to leave no stone unturned, and a home video of 9-year-old Shasta was released in hopes that the public may recognize her.

CBS News' Terri Okita reports that authorities have been following up on dozens of leads on the kids and the murder investigation, and that FBI profilers have now been assigned to the case to aid local police.

Kootenai County Coroner Dr. Robert West says 40-year-old Brenda Groene, her 13-year-old son Slade, and her 37-year-old boyfriend Mark Mckenzie all died quickly after being bound and beaten to death in their home. He's unsure what the weapon was and says it wasn't left at the crime scene.

"There was some evidence of illicit drugs and, in the two adults," West revealed in the toxicology report. He wouldn't specify which drugs and says no alcohol was found in their systems.

A $70,000 reward has been offered for any information, and this murder mystery and possible abduction will be featured on "America's Most Wanted."
