Playboy magazine founder Hugh Hefner, who died Sept. 27 at the Playboy Mansion, died of cardiac arrest and respiratory failure after contracting the blood infection septicema along with drug-resistant e. coli, People magazine reports, citing Hefner’s death certificate from the Los Angeles Department of Public Health.
Hefner was surrounded by his four adult children and his wife, Crystal, when he died. He was 91.
“Hefner suffered from a long-term back condition that limited his mobility,” People notes. “His former girlfriend Barbi Benton previously told People she last saw him six months ago and noticed that his memory was ‘fading’ — he admitted to being ‘in poor health.’”
Hefner was reportedly buried Saturday at Westwood Village Memorial Park in Los Angeles. “He was laid to rest beside Marilyn Monroe — the subject of Playboy‘s first centerfold,” the People report notes.
