What are Call Detail Records?

Call Detail Records (CDRs) are simply cell phone records. CDRs are created whenever a subscriber places or receives a phone call, text message, or uses data across the cellular network. These records can provide meaningful information to include which cellular tower(s) were used while accessing the network. The data provided by the service provider is unique to each company.

CDRs can be critical in a criminal or civil case. If you are litigating a case where CDRs are involved you need to retain an expert who can analyze the records, explain it to you, and ultimately to a jury in such a way they can understand it. Mark Pfoff worked for a phone company as a computer engineer, was a detective for many years, and is now a court qualified expert in CDR analysis, cellular technology, NELOS, police procedures and investigations.
