Over the last 30 years, Digital evidence has improved through technology and how investigators use different methods. When digital evidence was first discovered around 1984, it was used to examine computer evidence. A well-known case that was solved with Digital Evidence was "The BTK Killer". The case was solved by deciphering cryptic messages. Coding is used a lot throughout devices so it was important to have a method to solve cases like this. Technology such as a faraday box is used to store devices to prevent outside signals or any information from being deleted or changed in a device. I think that digital evidence is an invaluable resource because it can help make the process easier when collecting evidence and leading investigators to a possible answer. For instance, a certain email, search history, or transactions can help investigators come up with a better lead than having no information at all. The most valuable part of digital evidence is the information that is stored on the device. Without digital evidence, a lot of well-known cases wouldn't be solved making it easier for criminals to get away with things. As technology advances, it's important to have some things that can be used as a crime to be prevented. Having digital evidence can help prevent more crimes from happening in the future.

The case almost didn't go to trial due to it being seen as a suicide. Because of the lack of treatment for Kari's body after death, there wasn't enough evidence to prove that he murdered her at the time. There was evidence of her laying on the bed with sleeping pills next to her. It was also almost the anniversary of her daughter's death which is why there wasn't any suspicion.

The main witness in this trial was Vanessa Baker and Lina Dulin (Kari Baker's Mother). Vanessa provided all the evidence of what Matt did to Kari and explained everything in full detail. She described how she met Matt by seeing each other during church. She also described all the conversations and meetings she had with Matt that led up to Kari's death. Linda Dulin was the one who wanted to prove that her daughter didn't die of suicide and that Matt was the one who murdered her.

Four years after Kari's death, the case went on trial. During the trial, Matt Baker made an important statement saying, " I truly believe in my innocence. I believe the jury made a mistake." During the trial, the Judge went over the series of events that happened before and after Kari's death. They went over an important part which was Matt's search history on his computer. He said he was searching for an "overdose of sleeping pills". But it was seen that he was trying to purchase Ambien and to buy it you would have to search up "Ambien" or "Ambien without prescription". Matt Baker was asked by Bill Johnston (Linda's attorney) to plead the fifth amendment. He was asked if he was in a relationship with anyone before Kari's death which he replied no. Throughout the trial, Baker was not as talkative as he usually was which led to suspicion. He told attorney Moriarty that everything he said was the truth. On the third day of trial, Linda Dulin came to face with her daughter's murderer. She wanted an explanation on why he had murdered her and he stated, "I didn't kill her." On the last day of the trial, the topic of Kari's death was made. Matt didn't testify and still didn't admit to murdering Kari Baker.On January of 2010, Matt Baker was sentence 65 years to prison for the murder of Kari Baker.

What are the challenges that come with Digital Evidence?

# data[].attributes.body
With Digital Evidence it can be easily hacked or tampered with. If not kept protected, digital evidence can be lost. It is important to follow the chain of custody and make sure the evidence is being correctly handled. Some digital evidence, can be hard to read or decipher because of its quality. Quality plays a huge role in digital evidence such as videos or audio. It important to at least have a clear view of what the audio or image could be. Because of these challenges, it can easily be hard to analyze or be used against court.

Chain Of Custody for Digital Evidence and how it's preserved

# data[].attributes.body
The chain of custody for Digital Evidence is to collect,transfer, and analyze evidence. It is also important to document each person who was in contact with the device and have the time and date when it was transferred. To preserve the evidence, first you must make sure the evidence is left the way it was found. Next thing is to secure the device and making sure its in a well protected area. Digital Evidence is then preserved by placing the device into a Faraday bag to block any radiation.It is used to protect anything from being hacked or tampered with. The device allows for any digital evidence to be collected.

Encryption is information that is transferred into code so that only the people who made it know how to decipher it.It is also used to make sure that information can't be stolen or read. Decryption is used to break the code this usually happens in hacking when trying to unlock important evidence.

Digital evidence is presented in many ways such as, emails, audio transcripts, transactions, images, videos, and documents. Most digital evidence is found in search histories. It is important that any evidence that is used must not be changed. Any source of evidence that is found must be analyzed,examined and documented during investigation. It is then preserved and given to professional forensic scientist. Then the evidence goes through a chain of custody and kept until court.
