Using the GPS in Marcel's phone, we were able to construct a timeline showing where he was on Friday.
At approximately 10:03 AM, Marcel left his home, about 10 minutes later, he was at the Anytown Coffee Shop. He stayed until around 11:23 AM. He then passed the intersection at Ash and Maple (the entrance to his neighborhood). He was back at his house at around 11:35 AM and stayed until 3:30 PM. He then drove straight to work, arriving at around 3:50 PM. He worked his normal shift, staying until 10:04 PM. He got home at 10:28 PM and his phone had never left his house since then.

After following the processes of a gross examination of the heart, we found no impairments of significance that would indicate that this death is the result of heart related defect. There are no noticeable occlusions and the interior of the heart seems to be healthy. We can conclude that the death of Marcel Newgard was not the result of any heart related problems.

# data[].attributes.body
After viewing both the decedent's nervous tissue and an anatomical image of the brain, we can diagnose the decedent with a traumatic brain injury, or TBI, for short. In reference to the anatomical model of Mr. Newgard's brain, we can see that in comparison to the control there is large discoloration and swelling in the bottom right lobe. The lower left lobe shows no signs of regression, however, there is very clear damage in the bottom right lobe of the brain. This leads us to believe that Mr. Newgard suffered some kind of head injury that contributed to his death. The baseball bat beside the corpse insinuates that the bat may be the weapon responsible for this damage, however, the substance on the bat was confirmed to not be blood which leads us to believe that this may not be the case.

# data[].attributes.body
The presumptive blood tests confirmed that the substances found on the baseball bat and the car were confirmed to not be blood. Contrarily, the spatter was confirmed to be blood and not a near replica. After undergoing confirmatory blood testing, we were able to discern that the blood type of the spatter was type-A which narrowed down the list of whom the blood could belong to. This data allowed us to shorten the list of suspects of the blood to Marcel Newgard, Kay Litrell, and Jenn Newgard. We then underwent gel electrophoresis to completely identify the suspect of blood. We were able to match the DNA of the splatter to Marcel confirming that the blood belongs to the decedent. We then underwent gel electrophoresis to completely identify the suspect of blood. We were able to match the DNA of the splatter to Marcel confirming that the blood belongs to the decedent. We were also able to trace the DNA of the gum to Kay Litrell which may have no significance to the death but it helps to determine that she was there at some point.

Cam says he last saw Marcel on Friday afternoon at 3:30, just before Marcel left for work and Cam left town for the weekend to visit family. He and Marcel recently had an argument over Aiden.

# data[].attributes.body
The decedent was pronounced dead at the scene by a medical examiner at 2:00 PM. The examiner had noticed no signs of rigor mortis, however their was fixed lividity on the front side of the decedent's body, and the body had a slight green discoloration. At 2:30 PM the same day, the examiner had taken a rectal temperature and ambient temperature of the garage, both turned out to be 93 degrees Fahrenheit. Insects of all stages were also found on the face of the decedent. Using the Glaister equation, I determined that he was dead for approximately 3.6 hours before he was found by the medical examiner.

22 years old, female; Marcel Newgard’s coworker at the Biotic Bistro restaurant

Kay says she last saw Marcel at their Friday shift at the restaurant; they both clocked out at 10:00 p.m. Kay recently accused Marcel of stealing her tips and threatened to go to their manager.

The decedent, Marcel Newgard, was found with a 30 mg/L blood concentration of Organocarbamide. A lethal dose of this substance is anything over 9mg/L. This is a clear representation of the cause of death as this is a dosage of Organocarbamide that no human would be able to withstand. With this piece of evidence, we can infer that the rat poison was either taken as a method of suicide or it could have potentially been forced down the decedents mouth. There is also the chance of an accidental death, however, that is unlikely as it would be hard to ingest that much of that substance willingly.

Kay Litrell claims to have last seen Marcel at work on Friday, where they both clocked out at 10:00 PM. She had recently accused him of stealing her tips and had threatened to go to the manager (Naomi Lee) about it.

# data[].attributes.body
Due to the presence of the organocarbamide, we can conclude that this death was a result of suicide as there are no signs that anybody else was present at the time of death. We initiated a multitude of tests regarding, blood evidence, DNA sampling, toxicology reports, brain anatomy, and heart examinations. Through these reports, there is far more evidence to suggest that this death was an instance of suicide. Because of this, we believe it is of our best interest to close this case. We will notify the decedent's family of our findings and will therefore halt further police investigation.

The decedent had a cell phone with him at the time of death. There is a car parked next to the decedent with traces of a substance also confirmed not to be blood. There is a large gash on the decedent's forehead with blood pouring out of it. There is a noticeable blood spatter next to the decedent that has been confirmed to be blood and not a similar replica. Fixed lividity was found on the front side of the body, however, all signs of rigor mortis were gone. Insect activity began and blue-bottle flies were identified on the corpse of the decedent.

The fingerprints identified on the baseball bat found at the scene have been linked to both the decedent, Marcel Newgard, and his friend, Cam Banks. The minutiae found on both prints is an identical match to the samples of both Marcel and Cam's fingerprints. This finding adds to the theory that Cam may have more involvement in this case as previously thought. There is the possiblity that Cam used the bat as a murder weapon, however, there is the ingestion of rat poison to take into consideration so we cannot absolutely confirm anything as of yet.

After thorough examination of each individual suspect's strands of hair, we were able to narrow down the potential owner of the hair found at the scene to 2 suspects. Kay Litrell and Aiden Santori both have hair samples that are nearly identical to the sample found at the scene. After further examination, we are leaning more on the side that the hair sample is Kay's because the width of the hair found at the sample is closer to that of her's than it is in comparison to Aiden's hair sample. We cannot completely confirm that it is Kay's hair as Aiden's sample is still largely similar to the hair found at the scene, however, we are inferring that the sample at the scene is Kay's.
