Can you predict killing sprees? What do mass killers have in common? Why do so many of them write manifestos online, and what do these tell us? These are some of the questions David J. Krajicek seeks to answer about mass killings, a topic that is becoming increasingly urgent and desperate. In recent decades, mass shootings worldwide have increased in their savagery and frequency.

New York Times best-selling author and former federal prosecutor Lis Wiehl uses new research and first-hand interviews to tell the heart-pounding story of Charles Manson’s horrific crimes, the painstaking investigation that followed, and the inspired prosecution that put him away.

In the summer of 1969, Leslie Van Houten and Patricia Krenwinkel carried out horrific acts of butchery on the orders of the charismatic cult leader Charles Manson. At their murder trial the following year, lead prosecutor Vincent Bugliosi described the two so-called Manson Women as "human monsters". But to anyone who knew them growing up, they were bright, promising girls, seemingly incapable of such an unfathomable crime. Award-winning journalist Nikki Meredith began visiting Van Houten and Krenwinkel in prison to discover how they had changed during their incarceration.

Prosecuting attorney in the Manson trial Vincent Bugliosi held a unique insider's position in one of the most baffling and horrifying cases of the 20th century: the cold-blooded Tate-LaBianca murders carried out by Charles Manson and four of his followers. What motivated Manson in his seemingly mindless selection of victims, and what was his hold over the young women who obeyed his orders? Now available for the first time in unabridged audio, the gripping story of this famous and haunting crime is brought to life by acclaimed narrator Scott Brick.

Perhaps the most notorious American murderer of the 20th century, Charles Manson's legacy extends far beyond his horrific crimes. As the wild-eyed, swastika-tattooed, nightmarishly charismatic leader of the Manson Family, he was convicted of the brutal killings of nine people in 1971, including the Tate-LaBianca murders of seven in Los Angeles over two hot August nights in 1969.
