GUILTY!
I find this man to be EXTREMELY guilty. For one, his stories completely don't fit together. They always seem to change, even just a little bit. Also, where he had said that his daughter wet his side of the bed, the DNA tests came back as not a match to Kristen. I think this guy just got really angry at his wife and kids, and killed them. They already stated in one site that his pathological narcissism cause him to convince himself that there had been intruders, but the intruders were his family.

INNOCENT!
Tahlisa Brougham
After a more thorough examination of the case, I have decided to stick with my original conclusion – innocent. This is primarily because of the tampering, dismissal, and suppression of evidence by the prosecution. These tactics both prevent a fair trial and suggest those involved (lawyers, government, army members?) have something to hide. Most interesting, perhaps, is that the CID ignored a potential suspect, Helena Shockley, who fit the crime physically and personality-wise. They decided to withhold knowledge of her from the FBI, and later dismissed her open confession to being involved by saying she was crazy and incompetent. However, Helena could describe the MacDonald household perfectly and she admitted burning a blonde wig, boots, and a floppy hat (in accordance with MacDonald description AND an investigator’s description of a women he saw on the way to the crime scene). Blonde wig hairs were even found at the crime scene in an area that MacDonald claims to have seen the women, and the woman was a drug addict. She could have easily said, “Acid is groovy”. Yet, the woman’s potential relevance to the crime was hid and ignored. (http://karisable.com/mac7.htm, http://www.themacdonaldcase.org/index.html )
This was not the only evidence that could have lead to a solution and that was not brought into the light. Hairs under both of the children’s fingernails were found that did not belong to MacDonald, and one was bloody. Neither of these were presented in the trial. Also, after four years of the defense trying to get their hands on the evidence from the lab, they were finally allowed to look but not to test anything. They were not allowed a fair examination of the evidence. (http://www.themacdonaldcase.org/index.html )
Directly in the defense of MacDonald, without criticizing the methods of others, some of the claims against him, such as his hair and fibers being places can be justified by the simple fact that he lived in the house and had contact with his family. For example, if fibers from his pajama shirt were found under the nails of his daughter, maybe she clung to him while he carried her to bed.
Even if Jeffrey was actually guilty, you can’t prove a man guilty when you use unfair law practices, destroy evidence, and don’t give both sides of the story a real chance in court.

Dr. MacDonald was guilty of commiting the crimes of murdering his pregnant wife and two daughters. There is more than enough evidence justifying this conclusion. All of the murder weapons were ditched out the back door. Fibers from his shirt was found under each of the bodies. There was several motives found whether his wife was cheating, hit him or his daughter wetted the bed, Also he was found to have a list of mental ailments that would aid in his role of commiting the crime. His story changed several times during the trial. He passed a polygraph, but that can be passed by many people and with the lsit of mental ailments he may have been able to convince him self that he was innocent which would aid in MacDonalds passing of the polygraph. No sign of struggle was found down stairs where he fought the assalents except a knocked over planting pot and a flipped table. His pajamas where found to have straight holes rather than jagged ohles that would be present if he used it to ward off the assalents. Also why did they leave him alive but kill the rest of the family. This all points to him being convicted of being guilty of murder. Also the left handed person and Helen may have been co-conspirators in the murder which explains the three weapon types and wounds. The left handed person weilded the blunt board used to beat the women. Helen used a knife and MacDonald the ice pick. He was found to have a concusion and several stab marks and scrapes. The concusion could have been from being struck with the board and the stab wounds from Helen. The co-conspirators turned on him after the murderes for an unknown reason. Also he fake cried when on the stands and didn't display any emotions for his family when shown the photographs. An innocnet man would at bare minimum show some emotion to the pictures of his dead family.MacDonald was a conspirator in the murders and was helped by two other assalents that were not convicted.
He was however given an un fair trial due to poor investigation and inproper projedure.
Kayla Benson-
I really find Jeffrey MacDonald to be guilty of committing the murders. For one, his stories NEVER match up. On the first site given, http://en.wikipedia.org/wiki/Jeffrey_R._MacDonald, it states that he saw intruders but he could only describe what the woman was wearing. BUT, on this website, http://www.themacdonaldcase.org/Case_Overview.html, it goes into more detail about what each person was wearing. How can you say what each was wearing, if you could only see what the woman was wearing?
On the website that Kaitlin posted, http://www.thejeffreymacdonaldcase.com/html/memo_mcnamara_1973-06-26.html, it goes into a lot of detail about evidence given. The excuse for sleeping on the couch because his daughter Kristen had urinated in the bed had been proved wrong because when DNA checked, it didn’t match with the Type O blood that Kristen has. Though, it would match up with the DNA of a person with Type A blood (Colette) or Type AB (Kimberly). It also goes on to say that it would most likely match better with a person of Type AB DNA, meaning that it’d have to have been Kimberly to “wet the bed” not Kristen. Also, in this link, it goes on to say how the blood type of all these people had been found in all the room. This means they had been moved from the room they were killed in, to the room in which they were found. Why would any murderer want to move their victims’ bodies to a different room? What satisfaction does that bring to them?
Also, on another site, it goes on saying that the intruders had stuck around until the phone rang; Helena picked the phone up, while the others left. Why would they stick around in a house in which they murdered basically four people, if you count the unborn child Colette was carrying? Would it bring them joy, happiness? No, that’s honestly completely stupid. If I were to murder someone, I’d want to get out of that house as soon as possible, not stick around. So unless these were REALLY stupid intruders, I don’t believe it. http://www.themacdonaldcase.org/Case_Overview.html.
On an interview he does he sounds all confused as what to say about his recollection of that night. He seems to contradict himself many times. At one point he states about sleeping on the couch, and when he woke up, he could see people at the foot of the bed. How is that possible when he’s sleeping on the couch? Also, this contradicts with what he has said as a story in a link above that he had woken up to the intruders surrounding him on the couch. Unless they’re magical, they can’t be in two places at once. http://www.thejeffreymacdonaldcase.com/html/interview1970.html To me it seems as though he was trying to say the right thing. Just say anything to clear his name.
In the links above, it goes into detail about fibers being found from Jeffrey’s nightshirt are all around where the victims’ bodies were. They even found a fiber from his shirt under the fingernail of his daughter Kristen.
I do believe that he wasn't given a fair trial, and should've been found innocent though.

Guilty
Dr. MacDonald is guilty based off the evidence collected at the crime scene. Also there may have been one or more other conspirators involved in the murders, which explains the three weapons used. The girl that he described turned on him after the murders resulting in the bruises and wounds that he suffered, which explains why he ratted her out. Also his story was flawed and changed over time pointing to him being guilty.

Guilty
I agree tha he comitted the crimes and that Helen was involved, help committee the crime, also the lef thanded person was also involved with the murders. His story of the girl may be true because she may have turned on him after they murdered his family.

The courts sould have ruled him innocent because of the faulty technicues used, lack of evidence collected, burning the evidence, the brown haired man, the Investigators use of his person property. This all should have made his innocent in the courts due to flawed investigation.

Guilty!
I agree, I belive MacDonald committed the murders and may have been helped by the lady suspect. However in court he should have been proven innocent due to the faulty investigation and poor conduct performed by the Crime Scene Investigators.

Helena Stoekley may have help committee these crimes and then turned on him, which would explain his wounds.
