In March 2004, the Wichita television station received a letter

containing clues of the BTK murder. Alongside the letter was a box

containing a graphic description of The Otero murder.

Use of forensic techniques

DNA analysis:

Dennis Rader’s daughter offered up a DNA swab when she suspected her

father had something to do with it. The DNA was a close match to the

semen found at the crime scenes. A forensic serologist was brought in to

collect the DNA for processing and comparison.

Handwriting analysis:

The police brought in a handwriting specialist to study the letters BTK

sent in and matched them to the original one. This helped distinguish the

suspect who was suspected of the BTK murder but wasn’t.

Technology:

The police had to use the forensic technology specialist to hack into the

diskette that Rader sent to the police. When they hacked it, they found the

name “Dennis” and a few church documents. This was the pivotal proof

that helped in locking up BTK.

Utilization of digital forensics:

Through the use of the EnCase software, in unveiling the details regarding

the recent activities involved in the floppy disk, there has been a whole lot

of room to sue Dennis. The EnCase software, in this case, turned out to be

a very important tool. The software is designed for forensics, cyber secu-

rity, and e-recovery. The section of e-recovery is accustomed to

recovering deleted electronic evidence that may be used to document

concrete evidence of crimes; electronic evidence in most cases is free from

doubt. This explains why Dennis could finally have confessed to

committing crimes.

Therefore, computer forensics plays a major role in tracking down

evidence, especially those that have some digital concepts or links. It is

possible to trace all crimes through the use of forensic techniques.

Sentencing:

In February 2005, Dennis was convicted. He confessed all his monstrous
