15 Killers Who Just 'Snapped'

Updated April 28, 2020 256.3k views15 items

It's a phrase heard often in murder cases, in reference to people who suddenly lost control and committed awful crimes: "They just snapped." Although these incidents are generally the culmination of a long descent into insanity, for loved ones of the killers and victims alike, it often seems that they just spontaneously "snapped." Accounts of normal people who went crazy seemingly out of the blue have cropped up in the news for decades, and in every case, the shocked reaction of those who knew these individuals is the same.  

There are patterns evident in many of these cases; however, in some circumstances, no history of mental illness or violence had been established in the killers prior to their murders. These 15 stories of people who snapped and killed people cover both ends of the spectrum, where a clear path can be seen leading up to the "snapping," and where there is no path at all.

    In July 2007, Steven Hayes and an accomplice, Joshua Komisarjevsky, invaded the Cheshire, CT, home of William Petit; Jennifer Hawke-Petit; and their daughters Michaela, 11, and Hayley, 17. Hawke-Petit was battered and tied up in the basement. Hayes then forced Hawke-Petit to extract a large sum of money from an ATM before leading her back into her home. When Hayes returned, he and Komisarjevsky sexually assaulted Hawke-Petit and Michaela and strangled Hawke-Petit to death.   

    The men then set fire to the house and fled. Michaela and Hayley were burned alive. Hawke-Petit, however, managed to escape the fire, and helped to put Hayes and Komisarjevsky away. Hayes claimed he had no memory of the incident until a year later and says he "just snapped' and became someone else when committing the crimes.

    Robert Cromwell of Springfield, OR, had planned a romantic evening with his then ex-fiancée Casey Lynn Wright, hoping to rekindle their relationship. However, Wright admitted that she had already met someone else and things took a disturbing turn. According to a report by Josephine Woolington of The Register-Guard:

    "Cromwell... searched her cellphone after she fell asleep and found text messages from the man referenced by Wright as well as from another man. Cromwell then told Detective Don Myers in the video that he struck Wright four times in the head using an aluminum baseball bat while she was sleeping in the Springfield home that the two previously had shared. 

    Cromwell told Myers in the video that he didn’t want to wake Wright up. 'I didn’t want her to see me doing it,' Cromwell said."  

    Cromwell had a history of mental instability, including a previous suicide attempt, and had been on antidepressants and had nightmares and a drinking problem prior to the incident.

    In 1996, Glendale, MO, resident David Barnett murdered his grandparents, Clifford Barnett, 82, and Leona Barnett, 75, stealing their car and $120. He collectively stabbed them 21 times, using five different kitchen knives for the grisly task. 

    Barnett confessed to the crime the next day, telling police he had not planned the murders, but that he felt a "rage" well up within him, which caused him to snap. After an initial death sentence, a judge commuted Barnett's sentence to life in prison, after facts about Barnett's horrendous childhood came to light.
