An intimate look at the internet killer featured in the Netflix true crime documentary Don't F**k with Cats—written with the murderer's mother. In 2012, male escort and porn actor Luka Magnotta found a gruesome path to fame. He videotaped himself murdering and dismembering Chinese student Jun Lin before posting the video online. After mailing Jun's hands and feet to elementary schools, Luca led Interpol on a manhunt that ended in Berlin. They arrested him at an Internet café where he was reading news stories about himself. Now with a legion of twisted fans, Magnotta was brought back to Canada, convicted of first-degree murder, and sentenced to prison. During this time, Anna Yourkin, his estranged mother, troubled by Magnotta's abused childhood and her role in it, reconnected with her killer son. With exclusive interviews, Magnotta has given award-winning journalist Brian Whitney an intimate look inside the mind of this "social media" killer. Joining Whitney to tell this unique true crime story is Anna Yourkin, who provides exclusive photos.
