- 1949 January, two people identified the body as that of 63 year old former wood cutter Robert Walsh. This possibility was ruled out as the dead body looked too young to be Walsh.

Jestyn's residence was only half a mile away from where the dead body was found. The book contained one penciled telephone number plus a sequence of 50 letters presumed to be a secret code. The sequence is in 5 lines and contains 3 spaces. One line is possibly crossed out.
- 1949 July 25th, SA police test the "Tamám Shud" paper against the colour and texture of the paper in the book found in the car. They confirmed a match. A copy of the code is sent to Army Headquarters in Melbourne for an attempt at decryption.
- 1949 July 26th, Police trace the phone number in the book to Jestyn, and they show her the plaster cast of the victim at Paul Lawson's office. Lawson's diary entry for that day names her as "Mrs Thompson." According to newspapers, she stated she was unable to tell if it was Alf Boxall or not. Lawson describes her as a short lady. She dressed in light coloured clothes that day. She had a nice figure, and according to Lawson she was "very acceptable" (referring to level of beauty).

- 2009 March 19th, Dr Matthew Berryman notices rocks placed at the foot of the Somerton Man's grave in the Jewish tradition. The Somerton Man himself was not Jewish, as he was uncircumcised. This most likely indicates that a Jewish person visited the gravesite in recent years.
- 2009 March 19th, Prof Derek Abbott checks Adelaide Uni/RAH Pathology Autopsy Reports of 1948 and 1949, finding that there is no entry for the Somerton Man. Next step is to check Coroner's office for them. Also the Barr Smith Library's collection of Cleland's notes did not contain anything on the case.
- 2009 March 27th, ABC Stateline broadcast a story on the Somerton mystery. See video link here.
- 2009 March 31st, Andrew Turnbull and Denley Bihari give a seminar on the Somerton mystery at the University of Adelaide, proposing a number of code cracking approaches. The talk was attended by Gerry Feltus, Tony Elliot, and an ABC film crew.
- 2009 April 6th, Prof Derek Abbott puts out a world-search for an identical copy of the Rubaiyat of Omar Khayyam to that of the Somerton man, using the power of FaceBook. No one in 60 yrs has ever found or come forward with an identical edition of the book. To see the world-search go here.
- 2009 April 15th, Prof Derek Abbott finds that the Coroner's office has no autopsy report on the Somerton man.
- 2009 April 28th, Prof Derek Abbott consults an expert on ears and finds the Somerton Man significantly has a cymba larger than his cavum. This feature is possessed in only 1-2% of the caucasian population.
- 2009 April 28th, Prof Derek Abbott has a microscopic analysis of the original "Tamám Shud" piece of paper performed and compares the paper fibres to a Whitcombe and Tombs copy of Omar Khayyam from the same period. It is found that the "Tamám Shud" paper from the dead body, by comparison, has a larger surface roughness. Also under the microscope, the "Tamám Shud" paper appears to have quite a lot of dirt and contamination on it, but this could be due to poor handling and storage since 1948.
- 2009 May 5th Prof Derek Abbott consults dental experts and concludes the Somerton Man had anodontia of both lateral incisors from a young age and possibly birth. This feature is present in only about 2% of the general population.
- 2009 August 7th, John Harber Phillips dies.
- 2010 June 16th, Prof Derek Abbott tracks down a clear newspaper photo of Jestyn's son showing a clear shot of ears and teeth. The photo clearly demonstrates a small cavum and low crus helicis like that of the Somerton Man. Also the teeth show andontia of the lateral incisors like that of the Somerton Man. Prof Derek Abbott estimated that the null hypothesis that this is merely a random coincidence would be very small somewhere between 1 in 10,000,000 and 1 in 20,000,000.
