Investigate some of the most unbelievable yet relatively unknown true crime stories in Unbelievable Crimes Volume Ten.

In the tenth installment of the series, I'll cover more macabre cases that are lesser known.

One such case follows the story of an American-Australian serial killer who embarked on one of the most brazen murder sprees in recent history.

I also cover the tale of a murderous couple who plucked young women from the street for their own sinister desires.

Then there's the tragic story of a vulnerable young woman who was entangled with a dangerous young man. This case ends how you may imagine - though the brutality in which her life was ended is beyond comprehension.

Learn about these cases and more real-life tales of terror in Unbelievable Crimes Volume Ten.
