High-Tech Crime Investigation


Computer Crime Investigations

Computer technology now encompasses mobile devices, tablets, laptops, desktops, and more. As an investigator, you need a working knowledge of this technology, its application to criminal activities, and the issues associated with investigating these cases. Learn more


Digital Evidence Investigations

Digital evidence is everywhere. From security camera footage that shows a suspect entering a building to a teenager’s cell phone that shows how many times she (unwittingly) texted a registered sex offender—it’s all potential evidence. Learn more


Digital Evidence: Legal Procedures & Practices

As technology continues to cast its shadow on nearly every case, are you as prepared for court as you should be? As a prosecutor, are you aware of the latest case law for authenticating emails, chats, and other digital evidence? Learn more


Social Networking Sites & Investigations

Information available on social networking sites like Facebook and Twitter has the potential to impact every area of an investigation. With the right skills, you can find information about suspects, victims, witnesses and possible co-conspirators. Learn more


Wireless Networks & Volatile Data

Volatile data is data that requires power to maintain its existence. If power is removed from a device, the volatile data is erased and gone forever. As an on-scene investigator, it’s likely that you are often faced with processing live crime scenes. Learn more

From Bits and Bytes to Friends and Likes

SEARCH has a long-standing national program of providing mission-critical training and technical assistance to law enforcement, including Internet Crimes Against Children (ICAC) Task Force members.

Since the mid-1980s, when we first created the National Criminal Justice Computer Laboratory and Training Center, we have trained thousands of investigators. One of our first courses was called Data Processing for Law Enforcement Managers. It presented course content that was critical to investigators who were just beginning to use computers, and also was one of the few ‘high-tech’ courses then available to law enforcement.

As technology reaches into nearly all areas of our lives, law enforcement officers are challenged to maintain the skills and tools needed to conduct thorough investigations. Breaks in a case often come only at the expense of perpetrators who make mistakes. But investigators who are unfamiliar with digital evidence can overlook even these kinds of breaks. That is why we are committed to developing and offering courses that help to digitally empower today’s law enforcement community.

“I had never taken a cell phone data recovery class before and had only received informal training on the job. This was an excellent introduction to the tools used in extracting data from mobile devices and will serve me well in the future.”
“The course was very well constructed and professionally presented. The tools I have at my disposal now will have an incredible impact on my assignment and my agency.”
“I thought the class was fantastic. I learned more about online searching in the last two days than I have in the last 18 years.”

Casey, and Hewlett. Prior to joining SEARCH in October 2020, Ms. Lissy served as a Social Science Researcher at RTI International, as a regional Crime Analyst for the Redmond (WA) Police Department, and as Director of a research program with the Harvard Center for Risk Analysis. Beginning in 2012, Ms. Lissy’s work has focused on improving data in law enforcement to answer policy questions and improve community/police relations.
