A report is circulating from credible ICT/ internet forensics consultancies that mapped Kohberger's social media. These state Kohberger was connected to two victims via online activity. An analysis of Kohberger's accounts was done by Garrett Discovery, a computer and social media forensics consultancy:

The report, linked here (opens pdf) shows Kohberger's accounts had interacted with two victims' accounts - MM and KG:

The chief executive of ShadowDragon which specialises in software to analyse online activity and social media connections in criminal investigations, has commented on the analysis. ShadowDragon software was used as part of the analysis:

I have no expertise in computer/ social media forensics and post the analysis as a basis for discussion in the sub, but a few points are apparent from this analysis and the linked commentaries:

• The analysis used specialised software and Kohberger's email addresses and phone numbers to identify social media accounts associated with those. This was done in week 1 January 2023.
• The ShadowDragon SocialNet software focusses on identification of aliases and non-obvious connections to a target, to help investigators find that target's social media accounts that may have no obvious linkage to them.
• This is not "fake Instagram" accounts following victims; these are accounts linked to Kohberger via email/ phone info and the analysis appears much more sophisticated that looking at Instagram accounts named "Bryan Kohberger" of which it was evident, as fast as hours after the arrest, that many fake accounts using that name had been created.
• Twitter, cash apps and various other apps like AllTrails, Snapchat, Twilio etc appear to be used here to confirm linkage to Kohberger's emails/ phone numbers and by co-linking these various app accounts to each other the common link to Kohberger is further solidified.
• There are phone numbers used in the analysis different to the #8548 number detailed in the PCA; there is a 570-520-5889 number; this #5889 number is a PA AT&T number, confirmed as Kohberger's from the WSU staff listing (deleted after his arrest).This phone appears to predate the #8548 AT&T number which was active from June 2022.
• Various aliases e.g. "Bryan Slight" are associated with Kohberger's email/ phone numbers on some apps.
• The connections mapped by the analysis are not as simple or obvious as an Instagram account named "Bryan Kohberger" following a victim, but rather account(s) associated with Kohberger's emails/ phone numbers interacting in some way with victims' accounts. ShadowDragon described the social media linkage to Kohberger and the victims as hard to find without specialist software
• It is clear, despite premature defense claims, that an internet connection of some kind, whether anonymous stalking of profiles or more, between Kohberger and victim(s) cannot be ruled out as several search warrants were progressed and returned targeting Kohberger's and victims' social media accounts well after the defense claimed "no connection". Apart from the subjective and inexact nature of "connection", a link cannot logically be excluded when (i) search warrant returns happened later, (ii) the defence simultaneously claimed to not have completed review of discovery materials and (iii) discovery was and still is incomplete.
• In a follow up article on the ShadowDragon website, Clemens opines that Kohberger's social media usage fits a profile similar to other mass killers whose social media ShadowDragon had analysed, with a large amount of Kohberger's activity centred on women he objectifies. As one example, Kohberger following a prominent Florida plastic surgeon (Dr Ary Krau), whose socials mainly feature women post cosmetic surgery augmentation, was flagged as significant :
