Whether you are a true crime reader, or a criminal justice student, this Research is Ready for you! In Siblings who Murder, you'll read about twenty-one people who have either admitted guilt and are pending sentencing--or already tried and convicted. Included is a wide-range of situations from a 12-year-old boy who killed his 2-year-old brother to a 47-year-old woman who murdered her older sister and stole her identity. Also included are people who not only killed their sibling(s), but murdered their entire family. After the last chapter, you'll see the data sorted in multiple ways. The same twenty-one killers who are in this book are resorted into new grouped lists. The first is by dates of murder(s), then the age of the killer at the time of the murder(s), the next is by geographical location where the crime(s) occurred, and the last is grouped by weapon(s) of choice. Resources are included within each topic area, whether they were used as a source, or not. The sources used are specifically cited, but there are a few extra resources listed so you have more information at your fingertips should you decide to read further on any particular case. There are at least four resources per case. Books in the Ready Research Series: Volume I: Mommies who Murder Volume II: Children who Murder Volume III: Serial Murderers Volume IV: Siblings who Murder Volume V: Spouses who Murder
