More evidence of child pornography on electronics seized from Thomas O’Grady’s home came from the stand at day two of his trial underway in St. John’s Provincial Court with testimony from police officer Mark McHugh.
Mark McHugh works in cyber security with the military, but in 2017, he was a Computer Forensic Examiner with the Combined Forces Special Enforcement Unit. McHugh specializes in electronic communications, data recovery and verification, and computer forensic analysis. He testified as an expert witness for the Crown yesterday.
In 2017 he carried out forensic analysis on electronics seized from Thomas O’Grady’s Kilbride home.
McHugh explained for the court the difference between finding accessible files on a device, or files that’s are readily available – and inaccessible files, or files that have been deleted. Using police software, McHugh searched an external hard drive found at O’Grady’s home. He testified he found 355 files that had been deleted that contained child pornography.
A search of a seized thumb drive netted 211 inaccessible files that McHugh says also contained child pornography.
He returns to the stand today.
