Titus told the court that, as a professional digital forensics examiner, her schedule is to analyze contents of various digital devices such as flash drives, hard drives, mobile phones, tablets, and all sorts of storage devices using a software or other tools in order to recover information contained in those devices, and ensure the integrity of such devices are not compromised.
The witness told the court that between June and July 2015, a team of investigators from the Economic Governance Section of the Commission came to the Forensics Department. She said the team, led by Detective Michael Wetkas brought a journal and asked if forensically, they could ascertain the actual date and the computer the journal was created from, and if the files created can be printed out. โI said, yes, if we have access to the system, particularly the hard drive where the information is stored,โ she stated.
She said the investigators returned to Dantata and Sawoe at Kargi and with the help of the Chief Accountant of the company, located the system from where the journal originated and, using a software, forensic imager light version 3.1, copied details of the information in the hard drive which they brought to the Laboratory for analysis.
She said she narrowed her search to ascertaining the originality of the journal from the system the documents came from. The witness told the court that she discovered it came from the same system. She said the journal given to her showed it was created between 2010-2013 and 2014-2015 and each journal contained a different worksheet. The first worksheet was named; 66012 and was saved on March 3, 2015 at about 9:18am.

She further told the court that among the workbooks she discovered on the system for 2010 entry, contained the journal entry and was named; SPEED, WADA and MAINA.XLXS.
While cross-examining her, Joe Agi SAN asked the witness whether the software captures deleted files. She answered in the affirmative but adds that she only did her checks and analysis based on the request she received from the investigators.
Justice Ojukwu thereafter adjourned the matter till January 24 and 25, 2022 for continuation of cross-examination and trial.
