Kevin Samuels, the polarizing YouTuber known for giving controversial relationship advice, has been trending on social media this past week after his unexpected death was confirmed by the Atlanta Police Department and his mother.

Officers were called to an apartment in Atlanta last week “regarding a person injured,” where first responders had already performed CPR on Samuels. A nurse in the apartment told authorities Samuels was experiencing chest pains before he was taken to Piedmont Hospital and pronounced dead. NBC News reports that the Fulton County Medical Examiner’s Office said he was 53 years old, while the New York Times writes that he was 57. 

Since joining YouTube in October 2015, Samuels earned 1.4 million subscribers and over 1.2 million Instagram followers, largely thanks to controversial views many deemed toxic and misogynistic. Some video titles include “Women Should Let Men Use Them,” “How Much Does Your Submission Cost,” “Modern Women Are Average at Best,” and “Women Love When Men Cheat.”
