Cell Phone Data - Criminal Defense Attorney Analysis - Idaho v. Kohberger

If the defense strategy will be to systematically attack the State's evidence, how will they approach and break down the cell site location information obtained from his phone records? As with all forensic evidence, the devil is in the details; so, we look at some of the questions the defense team is likely to be asking. After an overview of how the communications between cell phones and cell towers can be used to calculate the phone's position, we'll talk about the factors that can affect how reliable and precise these determinations are and why it's potentially a pretty different situation in Moscow, Idaho than in denser urban settings. We also see a hint in the probable cause affidavit that the cell data may not tell the whole story when it comes to determining Bryan Kohberger's location.
