The hospital where Owen was treated received more than 100 calls and telegrams from well-wishers within the first 24 hours after the fight. Owen's mother arrived in the United States a day later. The neurosurgeon in charge of Owen revealed how they had discovered that Owen possessed both an unusually delicate skull and a strong jaw. As a result, Pintor's punch had inadvertently pushed Owen's jawbone through his skull and into his brain, causing irreparable damage. Owen underwent a second operation soon after to relieve pressure on his brain but soon contracted pneumonia. Once this had cleared, a third surgery was required but Owen remained unconscious. Although his doctor believed his condition was improving, a second bout of pneumonia on 4 November ultimately ended his life at 24 years old with his parents by his bedside.
