Technology and connected devices touch nearly every facet of modern life, and they often hold key evidence in criminal investigations. “Every single case now involves some sort of digital evidence,” said FBI Supervisory Special Agent Steven Newman, director of the New Jersey Regional Computer Forensics Laboratory (NJRCFL).

Digital evidence can be on any device and can follow subjects almost anywhere they traverse in the cyber world. As such, digital evidence is key in Internet-enabled crimes, but it is also critical in cases that range from terrorism to fraud.

In May 2018, three New Jersey men were sentenced to prison for conspiring to provide material support to the Islamic State of Iraq and al-Sham (ISIS), which is designated by the United States as a foreign terrorist organization. The FBI became aware of the men’s activities through a tip from an informant, according to Special Agent Suzanne Walsh with the FBI’s Newark Field Office.

Once that tip was deemed credible, digital evidence became key to investigating the men’s motives. The digital evidence left on the suspects’ computers and phones was crucial to showing criminal intent in the actions the men took—from planning to travel overseas to viewing ISIS propaganda online.

Alaa Saadeh, who was 24 at the time of sentencing, was given 15 years for his crimes. The evidence investigators uncovered showed he was actively planning to join ISIS and had supported his brother’s travel, both financially and logistically, to pursue that same goal.

Alaa’s brother, Nader Saadeh, 23 at sentencing, was given 10 years; and a third man, Samuel Rahamin Topaz, 24 at sentencing, was given eight years. The evidence showed all three had viewed ISIS materials, maps, and videos, including videos that depicted executions. Their communications also contained evidence that showed their desire to join ISIS and revealed some of the efforts they took to conceal their activities.
