When police attempt to place you at or near the scene of a crime, one of the tools they may use is “triangulation” of your cell phone. Texas law enforcement agencies are not the only ones to use this type of evidence, but it is not as reliable as police and prosecutors make it seem. If you face a criminal charge based on this evidence, it can be challenged.
Triangulation uses three cell phone towers to attempt to locate a user. The coverage area that overlaps between the three towers locates a particular cell phone. The problem is that the triangulated area could be large or small.
At best, this provides officials with an area where an individual might be located. That does not necessarily mean that you were present at the scene of a crime. Even if you were in the area, that does not mean you committed the crime. Perhaps you loaned your cell phone to someone else. You, and/or your phone, could be in that area for any number of reasons.
