On another occasion, a steamer trunk spotted in the debris field was found to contain three musical instruments, a deck of playing cards, a diary belonging to one Howard Irwin, and a bundle of letters from his girlfriend Pearl Shuttle.[154] It was first thought that Irwin, a musician and professional gambler, had boarded the ship under a false identity. There was no record of him being among the passengers, even though a ticket had been purchased for him. It turned out that he had stayed ashore but his trunk had been brought aboard the ship by his friend Henry Sutehall, who was among the victims of the disaster.[155] The fragile contents of the trunk were preserved due to the interior being starved of oxygen, which prevented bacteria from consuming the paper.
