Phone & Data Resources

April 28, 2018 @ 8:00 am - 5:00 pm

Traditional investigative techniques and tools do not work as well as they used to. Locked devices stop most forensic tools from working. Court orders and subpoenas are no longer valid tools for criminal investigations. Companies are not storing text message content. But at the same time the amount of information available on a mobile device has increased.

This class will explore the methods of exploiting a suspect’s cellular phone, phone company records, and third-party data sources records to assist investigations involving narcotics trafficking, homicide, sex crimes, gang related crimes, identity theft, and other types of criminal activity. This class will increase law enforcement officers’ awareness and appreciation of the evidence and intelligence located in a mobile device and provides students with the tools and training to prepare search warrants to legally obtain that evidence. Each student will receive templates for search warrants for cellular phones, call detail records and other information, and contact information for cellular service providers. Topics may include:

  • Updated search warrant requirements and language for 2018 – no more court orders or subpoenas
  • Obtaining information from social media, communications, and gaming applications
  • GPS location records for Android and Apple devices
  • How to deal with slow responses from cellular, social media, and online providers
  • Bypass procedures for locked/password protected phones
  • Where and how to recover deleted data from smart phones
  • Locating stolen cell phones and investigating fencing operations
  • Determining a suspect’s new number when he dropped his old phone number
