Computer Forensics Cases

Computer forensics have played an important role in prosecuting numerous high profile cases. One example is the case of the "BTK Killer" or "BTK Strangler". Dennis Rader is a convicted serial killer, known as the "BTK Killer" who was found guilty through computer forensics.

Catching a Serial Killer

Rader killed ten victims between 1974 and 1991 in Kansas. Several other people were severely injured or narrowly escaped death by Rader. Rader sent taunting letters to police and local news outlets during this period, but then the case went cold.

Rader resumed sending letter to the police and local Wichita, Kansas media outlets in 2004. He subsequently sent in a floppy disk file. Through forensic analysis of the metadata within the file documents, investigators were able to retrieve a document that Rader believed had been deleted. The data was recovered using EnCase forensic software.

Using The Metadata

The information showed that the disk had been used by Christ Lutheran Church in Wichita, as well as a reference to the name "Dennis". Rader was president of the Christ Lutheran Church council. Police were quickly able to obtain this information via an Internet search. This evidence helped lead to Rader's arrest and subsequent conviction for the heinous crimes.

The BTK Killer case is just one example of the power of using computer data to solve crimes. There are thousands of cases that have been solved using computer forensics and many appreciative victims of crime that are grateful for the expertise of these professionals.
