Tonight... Get on the Record with Greta!

A "very sad conclusion" to the investigation into the mysterious disappearance of two teenage girls in Oregon. Police have positively identified the remains of both girls. The number one suspect in the case is already behind bars. How will the killer be brought to justice? And why did it take so long to find the remains? We'll have full coverage of this tragic story this evening. And we'll speak with Michelle and Patrick Knoph who were neighbors and friends of the murdered girls.

Then, she did what she thought was best for her children... Carol Carr shot and killed her two adult sons who were terminally ill with Huntington's disease, a degenerative genetic nerve disorder that causes involuntary body movement, dementia and death. On Friday Carr was  indicted on murder charges. But is justice really being served? We'll take a look at that question with Carr's criminal defense attorney Eric Hearn.
