Sam Rubin's cause of death revealed after beloved KTLA and Hollywood Uncensored host died at age 64

Beloved KTLA and Hollywood Uncensored host Sam Rubin's cause of death has been confirmed by a coroner months after his passing. 

The 64-year-old tragically passed away in May, with a new report from medical officials finding he died from a heart attack after he suffered a massive blockage to his coronary artery. 

Rubin was rushed to hospital from his Los Angeles home just hours after hosting his regular Hollywood news segment that morning. 

The multi-Emmy Award winner was a renowned figure in the news industry on the West Coast, and had covered entertainment, movies and TV for KTLA since 1991.

He was also well-known in Australia as a contributor to Channel Nine's Today show and Today Extra, and in the UK where he appeared on This Morning.

He was survived by his wife Leslie and their four children, and in a touching tribute KTLA said he would be remembered for his 'laugh, charm and caring personality.'

This is a sad moment , to know you are not here on this Earth. Your memory will be a blessing. Another beloved favorite! Thank you for your humanity.'
