The ABC's of Cell Tower Data !
Ladies and Gentlemen, first off, welcome to my Wall of Evidence (we'll get into that in just a second). Secondly, if you do any type of investigation work, and are not pulling cell tower data, you are missing a tremendous amount of leads and evidence!
While preparing for a investigator group presentation, I prepared a slide in which I give the "ABC's of Cell Tower Data". I'm going to be brief in my descriptions but I hope you get the idea. Here we go!
A = ALERTS
Cell Tower Data gives you a history of where the device has been. And it's not limited by a chip on a phone! Go ahead, get a whole year's records of the cell tower data and watch where that device went (try that with an ordinary cell phone dump). This data will alert you to new areas you need to cover to find additional evidence for your case. Is there a gas station with a video camera that could render some good video for your case? How about highway or toll cameras? Witnesses? Places of interest that you did not realize? The cell tower data can show you areas that you did not even know could be of help to your case. How about that one call all by itself? Check it out, it could be a pizza delivery made to the subject (yeah, you didn't' get that piece of data from the cell phone did you?). No, the towers gave it to you.
B = Bonding Material
This is substantive data that will not only link other evidence together, it will help build the wall of evidence you are needing for your client. Think of your case as a wall. Each brick is a block of evidence you have either for or against the defendant. Now, the cell tower data is the CEMEMT that can be used to bond the evidence together so that your case is rock solid.
C = Corroboration
When you are building your wall of evidence, the cell tower data can support your evidence. How? Say your subject has an alibi and witnesses, but no one will believe him or her. The cell tower data may be what you need to show "see, he ain't lying!" Or, your client may have fit the physical description of the bank robber, but...the cell tower data shows his device no where near the crime (and he swears it's always on him!). The tower data supports his claims. Ok, lets flip the coin: you have a receipt of him being in a store right down the street from the crime, blood dripped from his hand in the bathroom. Pull the tower data and viola! Does it show his device in the area of the crime? The cell tower data corroborates and "bonds" with the evidence you have. Slam dunk...let's see LeBron do that!
So, whether you are on the prosecution side or the defense side, the cell tower data is invaluable to your cases. So what's holding you back from getting it? The answer? Nothing but a warrant or a subpoena.
If you need help writing the warrants or subpoenas, my company specializes in providing exactly what you need to ask for. And...I can map the entire call detail records you get plus present them in a visual presentation. Just give me a call...864-962-7307.
If you are already a digital forensics examiner and want to get into cell tower data mapping, I can also help you there. Call me for more info.
Thanks for stopping by. Oh and next time you see a cell tower, just remember the power they hold for you and your client.
The Value of Cell Tower Data
Cell Tower Data or commonly known as Call Detail Records ("CDRs") are a treasure trove of data (evidence) that many attorneys and investigators miss or are unaware of. CDRs show data such as tower locations, sectors, numbers called or texted as well as many other important facets in how and where the mobile phone device was used.
In fact, the CDRs can give you important evidence that the cell phone cannot provide. Many attorneys and investigators give up if the mobile phone is not available or if the content retrieved gives them little to no evidence.
DO NOT STOP WITH THE PHONE! GO FOR THE CDRs! A mobile phone user can delete or wipe data from the phone, but they cannot wipe out the CDR data, which is held by the Cell Service Providers.
Now, how do you know if the CDRs you were provided by the Prosecution have not been altered or modified? This is where a competent, well trained professional CDR Analyst comes in handy. The Expert will be able to determine if in fact you were given the proper CDRs as well as the other accompanying data provided by the Prosecution.
My company is here to help. Even if you haven't been provided with the CDRs or want to get them because the other side failed to do so, I can help. I can assist your agency in the correct wording you need for your subpoenas as well as to the proper department to submit them to, saving you and your client time and money. Then I can take the data and map it out for you in a clear, concise and professional format that is state of the art and makes juries take notice.
Don't stop with the phone, get the CDRs!
