The Scene

-Garage (Marcel found facedown by car).

-Baseball bat with red substance (not blood) beside Marcel.

-Phone by Marcel's hand.

-Dirty Floor.

-Chewed gum under the car.

-"Blood" was found beside Marcel's head and on the door of the car.

-This scene indicates that because the substance on the car is not actual blood but splattered to look like blood, it can be seen as a possible homicide. It can be determined that the killer placed it to make it look like an "accidental" or "natural" death. For example, Marcel could have been leaving his home and then as he was about to get inside the car, the homicide could have taken place.

Based on the biological evidence provided, the cause of death can be determined as organocarbamide poisoning, or the ingestion of a fatal amount of rat poison.

This would have led to death via the shutdown of respiratory function due to both bronchorrhea [the excess production of watery discharge within the lung tissue], and respiratory edema [excessive fluid buildup within the lungs], as the fluid within the alveolar sacks would prevent gas exchange, resulting in death via internal suffocation in a matter of minutes. Both of these symptoms were present in the autopsy of the lungs, as there were signs of frothy buildup within the lung tissue, as well as bleeding in the structures of the respiratory tract.

The manner of death is determined to be a homicide.

# data[].attributes.body
The scene of the crime indicated the presence of three unknown substances, found on various surfaces, all of which mimicked the outward appearance of blood. The substances were located on the baseball bat found beside the decedent, in and around a large dent on the parked car's door, as well as on the floor around the victim's head.

Presumptive tests concluded that the substances on the car door and bat are not blood, however, the splatter near the head of the decedent is blood. Confirmatory tests are required to determine the person to which the blood belongs. It was found to be Marcel's blood.

Cam Banks

- 23yrs old, Marcel's Roomate

- Last saw Marcel Friday at 3:30PM, before Marcel left for work and Cam left for the weekend to visit family. Cam and Marcel had argued over Marcel's new friend Aiden, related to Aiden going through their kitchen cabinets in their apartment.

Polygraph data demonstrated a lack of suspicion related to questions about the decedent, with little suspicion overall.

# data[].attributes.body
Aiden Santori

- 25yrs old, Recent Friend of Marcel

- Last saw Marcel on Friday at around 3:50PM in the Bistro's parking lot, before Marcel's shift at the restaurant began. Very little is known about him, he rarely shares personal details with anyone and is a bit of a loner. Aiden was recently caught going through cabinets in Marcel and Cam's apartment.

Polygraph data demonstrated possible signs of suspicion, as there were large spikes in both heart rate and respiration rate towards the end of the interrogation.

# data[].attributes.body
Jenn Newgard

- 20yrs old, Marcel's Sister

- Last spoke to Marcel on the phone on Friday at 10:15PM. Jenn and Marcel had recently argued over Jenn borrowing Marcel's car.

Polygraph data demonstrated very little suspicion related to questions about the decedent, high numbers were likely due to nerves/grief over loss of brother

# data[].attributes.body
Naomi Lee

- 32yrs old, Marcel's Work Supervisor

- Last saw Marcel when he clocked out after his shift at 10:00PM on Friday.

Naomi called the police when Marcel failed to show up for two shifts in a row [Saturday night, Sunday morning]. She told investigators that Marcel was a hard worker and got along well with customers and most employees [Naomi was unsure as to why Marcel and Kay didn't get along]

Polygraph data demonstrated a lack of suspicion related to questions about the decedent, minimal suspicious overall

# data[].attributes.body
Kay Litrell

- 22yrs old, Marcel's Coworker

- Last saw Marcel when he clocked out after his shift at 10:00PM on Friday, she also clocked out at that time. Kay had recently been arguing with Marcel at work, she had accused him of stealing her tips and had threatened to go to their manager.

Polygraph data demonstrated moderate suspicious and spikes in heart and respiratory rate.

Case Overview

An adult male, further classified as Marcel Newgard (23 years old) was found in his garage on November 24th, 2024 with a large gash on the forehead as well as an evident nosebleed and green discoloration. There were determined to be no internal injuries other than the trachea and bronchi, which contained a frothy, bloody fluid. The lungs were also seen to be congested and visibly swollen. The decedent was also found with 30 milligrams of organocarbamide in his stomach (also known as rat poison), which is fatal if ingested by a human. This likely led to his respiratory issues, which prompted Newgard to bleed to death internally.

Law Enforcement/Recommendations

-As this case comes to a close, it is determined that the manner of this death is a homicide. A confirmed suspect can not be detected at the moment. Still, it is recommended that officers return to the most suspicious persons of interest (Aiden/Kay) and convict them accordingly in court.

# data[].attributes.body
Evidence Analyzed

-POI text messages and digital evidence (indicated possible relationships with the decedent).

-Hair sample (could be Aiden/Kay's hair). Indicated that they were at the scene.

-Fingerprints (Cam's on the baseball bat). Indicated that they share the baseball bat because they are roommates.

-Substances (car door, floor, baseball bat). The floor substance was Marcel's blood while the other substances were not. This means that they could have been falsely placed to cover up a murder.

-DNA evidence (gum on the garage floor). It was found to be Kay's. She could have been in the garage at some point in time.

-Brain autopsy was found to be normal (indicates his death had nothing to do with his brain).

-Heart autopsy was found to be normal (indicates his death had nothing to do with his brain).

-Brain tissue (appeared normal). This means he did not have a TBI or CTE that contributed to his death.

-Drugs in his system (rat poison, aspirin, and caffeine). It is determined that the rat poison contributed to his death, determining it is a homicide.

-Insect: Blue bottle (2nd Instar). Indicates a possible range of hours ago that the decedent had died.

# data[].attributes.body
Cam could not have killed Marcel, as he was out of town for the weekend when Marcel's death occurred [this information was discovered by investigators when he was asked about his personal information and whereabouts]. It makes sense for Cam's fingerprints to be on the bat, as he and Marcel shared an apartment and baseball equipment [their text messages would lead one to believe that they played baseball together frequently]. Cam would likely be an easy one to suspect, as he lived with Marcel, but Cam is not the culprit, as all the evidence points against him doing the crime.

It is possible, however, that Aiden or Kay were present at the scene of the crime, as Kay's DNA was found in the gum on Marcel's garage floor, and Aiden was acting incredibly suspiciously towards the other POI and was caught going through the kitchen cabinets.

# data[].attributes.body
Marcel was found with 30mg of Organocarbamides in his bloodstream, which is clearly over the non-fatal amount of 9mg.

# data[].attributes.body
-It is determined that Marcel died between Friday at 10:45 pm to Saturday at 4:30 pm. The exact time of his death can not be fully confirmed because of the temperature of the garage. A range of hours can be determined though because of the blue bottle insect found on the body.

# data[].attributes.body
Marcel's physical injuries are clear indicators of his manner of death. When observing his heart and brain, it can be seen that Marcel's heart looks identical to the healthy heart, showing no clear sign of injury or damage. His brain scans are the same way, as they look identical to a healthy brain, showing no signs of large spots of bruising/bleeding meaning that there was nothing wrong with Marcel's heart or brain that would have led to fatality. His brain tissue microscope slides also demonstrate no clear signs of a TBI or bruising in the cells. His autopsy report also explains that there are no signs of damage to his skull or bodily organs, except for the respiratory tract, which demonstrated signs of distress. It is unlikely that Marcel died of his physical wounds, like the gash on his forehead and the bleeding from his nose. He did present yellow-green skin coloration, which is a symptom of drug overdoses/poisoning and could be caused by the lack of oxygen to the cells. The toxicology report, was the main indicator of his manner of death, as the blood lab results indicated high amounts of fatal substances.
