Alec Cook is a former student majoring in Real estate at University of Wisconsin-Madison. While at the university he was a member of the Phi Beta Delta fraternity.

On October 17, 2016, Cook was arrested and charged with sexual assault against a woman in his apartment that occurred on October 12, 2016, in Madison, Wisconsin.

Police soon received reports from three other women claiming Cook had previously sexually assaulted them, after the first woman reported Cook.

Investigators executing a search warrant found several notebooks kept by Cook in which he listed his potential victims. Cops found more than 20 notebooks that they believe were kept by Cook, in which he identified potential victims and, shockingly, wrote in detail about how he planned to groom or stalk them.
