· At 1022 hours on 1 June 2006 the computer suffered a fatal system error. At that time, Drive F was installed in the computer alongside the existing disk. At the time, "Patrick Power" was logged on to the computer and was performing file maintenance operations.
· The computer remained off until the next boot which occurred at 1326 hours on 4 July 2006 (this corresponds to the time when the analyst in the IT Branch at the ODPP turned on the computer to examine it). The hard drive containing Drive F was not attached to the computer at that time. Between 1022 hours on 1 June and 1326 hours on 4 July, this hard drive had been removed from Dr Power's computer.
· Although the hard drive containing Drive F was not in the computer when it was booted up by the ODPP technician on 4 July, and was not found during the execution of search warrants on his chambers or home, it has been possible to reconstruct much of what was contained on the missing hard drive. It contained catalogued homosexual pornography, some of it with names strongly suggestive of it being child pornography. Some of the files bore names such as "Naughtyboyz - Weekend House Party, Two boys playing in bed hardons, Gay porn…threesome rape of blond boy, Boy fucked by dad, 10yo Indian boy loves his rubber dildo man fucks him hard, Gay porn young boy tied gets raped begs for them to stop, Two gorgeous young boys jerkoff cum facial and kiss".
· Located on the hard drive in the computer was a Quicken accounting automatic back up folder containing 31 video files of child pornography. These videos contained scenes of adult males engaged in a variety of sex acts with young children aged 10 years and less and with adolescents aged under 16 years including penetrative oral and anal sex, bondage and masturbation and sex acts between adolescent (meaning under 16 years old) males. The vast majority of the child pornography was homosexual, although there was one still image of an adult female masturbating an adolescent male's penis. The videos were of varying duration from a few seconds to 37 minutes, the average being about 15 minutes. Full details of the contents of the videos can be found in the annexures to the statements of Detective Senior Constable Laura Beacroft dated 11 September and 12 October 2006.
· Also located on the hard drive of Dr Power's computer was a database containing 28,981 thumbnail images, the vast majority of which were homosexual pornography (there were about 200 personal images of a non-pornographic nature). Of the approximately 29,000 images, 433 were of child pornography. The majority of these images depicted males under the age of 16 years and a much smaller number depicted males under the age of 10 years engaged in a variety of sex acts with each other, or males depicted in a sexualised context. Details of the 433 images are to be found in the annexure to the statement of Detective Senior Constable David Shaw dated 4 November 2006.
· Also found on the computer was a 188-page novel entitled - text removed - which contained a number of passages describing sexual acts between males under the age of 16 years. The document appeared to have been forwarded by email to Dr Power's computer. The relevant emails can be found in Annexure 17a, b and c to the Computer Forensic Analysis Report prepared on 6 September 2006 by Sergeant John McCulloch.
· Dr Power had on his computer a software application called - text removed - that enabled a user to share files on his computer with other uses on a network, such as the internet, running a similar piece of software. The examination of the computer located many file names with references to child pornography which indicated that the files had been downloaded to Dr Power's computer using - text removed -. There is no evidence, however, of Dr Power having distributed to any third person any of the files or material downloaded by using - text removed -.
· Dr Power had also "bookmarked" a very large number of internet web sites. Some had names suggesting that the sites contained child pornography Examples include - text removed -. Some of the sites contained links to sites containing child pornography. The full list of the bookmarks can be found in Annexure 15b, 15c and 16 of the forensic computer report referred to previously.
· Evidence was found on the computer of an attempt having been made at 0739 hours on 4 May 2006 to burn to 14 video files to a DVD. The disc session was extracted from the disc image file and was examined. Ten of the video files had names suggesting that they may contain child pornography (Annexure 11 to Computer Forensic Analysis Report) - names such as "Dave 13 yo masturbates, pre boys, preteen boys sex…fuck, 2 Thai preteen boys fuck in bamboo forest, Jap boy and Man in garden, Friends from Poland Part 3 (Pthc Gay Pedo)." Eleven on the 14 video files were corrupt and unable to be examined. The 3 that were examined all contained child pornography (see 4.5.3 of Computer Forensic Analysis Report).
