Digital forensics 'vitally important' to Bruce McArthur murder investigation: expert
Forensic examiners are working to unlock alleged Toronto serial killer's electronic footprint
Digital forensics experts are assisting with the investigation of alleged serial killer Bruce McArthur to unlock a trove of electronic data that may provide clues about how his victims died.
Earlier he told reporters at a news conference that "searches of online and cellphone activity" are part of this investigation, but would not confirm if police have seized McArthur's computer or cellphone.
It's not only important to preserve the evidence that's on there, then you have to do the analysis to try and link it all together.-Ryan DuquetteBased on what electronic devices are seized from a scene, Duquette says forensic examiners will start by making copies of "everything, including the deleted content" before they start using forensic hardware tools to preserve the integrity of the data.
McArthur was active on Facebook. His account has been disabled, but it previously catalogued his evenings out and vacations, Halloween parties, birthday dinners, concerts and trips to Mexico.
Younger men, who appear to be of Middle Eastern or South Asian descent, showed up in several of his vacation and nightlife pictures.
Duquette says forensic examiners will mine Facebook to see who someone is connected with, "what were they doing on social media and what groups do they belong to."
