6. The Story of Dennis Rader
Who is Dennis Rader?
Dennis Rader is an American serial killer who murdered ten people in and around Wichita, Kansas between 1974 and 1991.

7. The Story of Dennis Rader
He is known as the BTK killer. "BTK" stands for "Bind, Torture, Kill", which was his infamous signature.
He sent letters describing the details of the killings to police and local news outlets during the time period in which the murders took place.

8. The Story of Dennis Rader
Rader was under suspicion in the BTK case (unknown to Rader), so the police corresponded with him in an effort to gain his confidence.
Then, in one of his communications with police, Rader asked them if it was possible to trace information from floppy disks.
The police department replied that there was no way of knowing on what computer such a disk had been used, which was in fact not true.

9. A blue 1.44- MB Memorex floppy disk was enclosed in the package.
The Story of Dennis Rader
The BTK killer's last known communication with the media and police was a padded envelope that arrived at FOX affiliate KSAS-TV in Wichita on February 16, 2005.
A blue MB Memorex floppy disk was enclosed in the package.

10. The Story of Dennis Rader
Police found metadata embedded in a deleted Microsoft Word document that was, unbeknownst to Rader, on the disk.
The metadata contained "Christ Lutheran Church", and the document was marked as last modified by "Dennis".
A search of the church web site turned up Dennis Rader as being president of the congregation council. Police began surveillance on Rader.
The police also knew BTK owned a black Jeep Cherokee. When investigators drove by Rader's house, they noticed the black Jeep Cherokee parked outside.

11. The Story of Dennis Rader
The police now had strong circumstantial evidence against Rader, but they needed more direct evidence in order to detain him.
They obtained a warrant to test the DNA of a Pap smear Rader's daughter had taken at the Kansas State University medical clinic while she was a student there.

12. This was the evidence the police needed to make an arrest.
The Story of Dennis Rader
The DNA of the Pap smear was processed by the Kansas Bureau of Investigation at their laboratory in Topeka which provided a familial match to the DNA of the sample taken from the victim's fingernails, indicating that the killer was closely related to Rader's daughter.
This was the evidence the police needed to make an arrest.

13. The Story of Dennis Rader
On February 25, 2005, Rader was detained near his home in Park City and accused of the BTK killings.
At a press conference the next morning, Wichita Police Chief Norman Williams announced, "the bottom line ... BTK is arrested".
Rader pleaded guilty to the murders on June 27, 2005, giving a graphic account of his crimes in court.

14. The Story of Dennis Rader
On August 18, 2005, he was sentenced to serve 10 consecutive life sentences, one life sentence per murder victim.
In total, Rader would be eligible for parole after 175 years of imprisonment, in 2180.
He would be 235 years of age.

Dennis Rader is an example of a criminal that was convicted on the basis of computer-related evidence

18. Computer Forensics
Since the 1990s, few fields have progressed as rapidly as computer technology.
Technology and electronic data are a part of everyday life and permeate all aspects of society.
Consequently, computers have become increasingly important as sources of evidence in an ever- widening spectrum of criminal activities.

19. From Input to Output: How Does the Computer Work?
Computer forensics involves preserving, acquiring, extracting, and interpreting computer data.
Software programs are applications that carry out a set of instructions.

20. From Input to Output: How Does the Computer Work?
The central processing unit (CPU) is the brain of the computer – the main chip responsible for doing the actual computing.
The motherboard is the main circuit board within a computer.

21. From Input to Output: How Does the Computer Work?
Read-only memory (ROM) chips store programs that control the boot (startup) process and configure a computer’s components.
Random-access memory (RAM) is volatile memory, which is lost when power is turned off. Programs are loaded into RAM because of its faster read speed.

22. From Input to Output: How Does the Computer Work?
The hard disk drive (HDD) is typically the primary location of data storage within the computer.
Partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that different file systems can be used on each partition.
