Patrick Swayze’s Brother Sean Swayze Dead at 63

Sean Swayze, the younger brother of late Hollywood legend Patrick Swayze, has died … TMZ has learned.

Sean’s son, Jesse Swayze, tells TMZ … his father died on December 15 in the Los Angeles area.

According to the Los Angeles County Medical Examiner’s Office … Sean died of an acute upper gastrointestinal bleed and severe metabolic acidosis brought on by cirrhosis of the liver — severe scarring caused by alcoholism.

Patrick, of course, became an industry icon thanks to roles in “Dirty Dancing,” “Ghost,” and “Road House” before his death in 2009 following a battle with pancreatic cancer.
