The elder Disick's passing comes just two months after the death of Scott Disick's mother, Bonnie. This may be a case of death by heartbreak, as Jeffrey and Bonnie had been married for many years.
Scott is an only child, leaving only himself and his two children, Mason and Penelope, as survivors.
Jeffrey Disick, a Long Island real estate developer, passed on January 2. His wife Bonnie passed on October 28. Neither Scott Disick or any of the Kardashians have made any comments at this time.
Condolences to Scott and the rest of the Disick family. They certainly have had a very rough year.
