Case Study: The Alibi Defense - Cell Phone Forensics Proves Innocence


Jeremy Roberts, was accused of being involved in a robbery at a convenience store on the night of December 10th 2022. The store’s CCTV showed a masked individual resembling Jeremy’s build. Additionally, a store employee claimed to recognize Jeremy by his voice indicating he would frequent the store often. Jeremy, however, maintained his innocence, stating he was at a friend’s house in a different town, which was about 45 minutes away during the incident.

The Accusation:

The prosecution’s case was based on:

  • CCTV footage showing a person resembling Jeremy.
  • Eyewitness testimony from the store employee.

Cell Phone Forensic Investigation:

Jeremy’s defense team, believing in his innocence, hired Elite Digital Forensics to gather evidence. The primary goal was to determine Jeremy’s location at the time of the robbery using cell tower and cell phone location evidence.


  1. Cell Tower Data: Jeremy’s phone connected to a cell tower five minutes after the robbery. The specific tower was located 1.5 miles from his friend’s residence in another town and over 25 miles from the robbery location.
  2. GPS Data: GPS coordinates extracted from Jeremy’s smartphone pinpointed his location at his friend’s house during the approximate incident timeframe.
  3. Wi-Fi Logs: Jeremy’s phone had automatically connected to his friend’s home Wi-Fi network, further corroborating his alibi.
  4. Social Media & Messaging Apps: Timestamped messages exchanged between Jeremy and another friend on a messaging app indicated he was watching a movie at his friend’s place an outgoing message was located from Jeremy stating “ I am hanging at a friends house tonight”


Armed with the evidence from the cell phone forensics, Jeremy’s defense team presented the findings in court.

  • Given the precision of the location data, combined with the timestamped messages, it became clear that Jeremy couldn’t have been at the scene of the crime.

All charges against Jeremy were dropped based on the forensic evidence, highlighting the pivotal role of digital forensics in modern justice.
