Siblings kill together in disturbing murder cases
About Killer Siblings
A certain dance occurs when two people plot a murder together, and Killer Siblings delves into these types of homicide cases. It focuses on those involving siblings (and sometimes additional perpetrators) who murder strangers, acquaintances, and even members of their own families.
Some of the stories are about minors, making the cases even more disturbing, and the show provides insight into what can happen when two people feed off of each other, with tragic consequences.
Detectives and others involved in the cases share their investigation stories, victims’ loved ones detail their experiences, and police interviews and trial clips complete the stories, along with information on the family and criminal background of the siblings.
Even though it follows the formula of most true crime series, the show’s focus on killer siblings is the most unsettling aspect, that two or more people from the same family could have a predisposition for murder. It leaves viewers wondering, maybe nature is at work here.
