Anna has Atherosclerosis. Her artery walls have plaque and cholesterol buildup on them making blood flow harder and increasing blood pressure. Clots in her brain or heart could have caused her death.

# data[].attributes.body
Carbs, Lipids, and starches were found in her stomach, but no proteins. Blood glucose level was found to be 280 mg/dL from the 125 ml of partially digested food in her stomach.

# data[].attributes.body
Anna did not have any alcohol or drugs in her system at the time of death, nor was there any evidence of tampering after the time of death. There are also no tears in her clothing, meaning there was no struggle before her death. There was vomit on her shirt, edema of the ankles, distension of the abdomen, and an injury to her right temple. The fingernails are grey and blue due to oxygen deprivation.

By doing a lab on height and diameter of blood drop spatters it was determined that as the height a drop of blood fall from increases, the diameter of the spatter increases and then stabilizes at around 15 mm.

The spatter at the crimes scene dropped from 60-70 cm at 90 degrees. This was determined using the best fit line from the hight vs. diameter lab backwards, to find the height based on the diameter of the drop.

# data[].attributes.body
Using the Glaister Equation

(98.4 – measured rectal temperature)/1.5 = approximate hours since death

(98.4 - 92.4)/1.5 = 4 hours since death

11:00 am - 4 hours = 7:00 am time of death

Anna died around 7:00 in the morning

# data[].attributes.body
Only Anna and Erica have the matching reaction to the blood at the scene. The blood at the scene has B antigens, but not A, so is B blood type. Anna and Erica are the only suspects that also have a B blood type.

# data[].attributes.body
The hair at the crime scene had a dark brown, cortex, relatively smooth cuticle, and a dark brown continuous medulla. This rules out Erica and Anna because both of these samples had no medulla. Alex’s hair had large gaps in the medulla, and Doug’s hair had a very light brown cortex, so both of these suspects are also ruled out. Lucy’s hair sample is the best match for the hair found at the scene.

Female

Hispanic

Diabetic

Taking aspirin

38 years old

# data[].attributes.body
The unknown drug could not have been Ecstasy or Acetaminophen because both of these drugs turned yellow-brownish when exposed to indicator 2 while the unknown turned very dark purple. The unknown drug was not Hydrocodone because no bubbles were released with indicator 1 and 3 while they were released with the unknown substance, and also could not be methamphetamine because no bubbles were released with indicator 1. The only drug that is left is aspirin, which matches up with the observation of the unknown drug. This makes sense because she was having back pain, so it might have been used as a pain reliever, and it could have been used as a blood thinner for he diabetes. Aspirin could interact with the insulin and make her nauseous, or pass out.

She had diabetes, due to insulin on the floor

There were footprints

There was blood, throw up, and hair

Blood spatter at 90 degree angle

Blood on the table, likely she hit her head on the table, but only a small pool of blood

Description of Anna

Manner of death = Accident

As of right now, there is no evidence supporting a homicide or suicide, and it does not look like a natural death due to the blood and drugs found at the scene.

Anna could have taken too much aspirin for her back pain while also taking insulin, causing her to become hypoglycemic, she threw up on the floor, and passed out, on her way down she hit her head on the table and killed herself.

Anna was having fever so she took some aspirin but it interacted with her insulin and caused her to pass out. She fell over and a hit to the head from the cart killed her. The blood is from her head wound, the fingerprint is from Alex when he saw her previous night, and the hair is from Lucy when she came over to Anna’s house when they were still friends.

Anna was not bleeding from standing, so her head must have been at the height of 70cm, the table has blood on it and it is 70 cm. She must have hit her head on the table and started bleeding.

# data[].attributes.body
Blood - Type B, either Erica or Anna
Hair - Lucy
Fingerprint - Alex
Shoeprint - Anna or Lucy
Unknown Drug - Aspirin
Time of Death - 7:00 am
Blood Spatter Analysis - dropped from 60-70 cm at 90 degrees

# data[].attributes.body
The fingerprint does not belong to Doug or Lucy because they do not have a looped fingerprint. Alex’s fingerprint looks like the best match just judging by its overall shape and patterns. Under a microscope, the minutiae could be looked at to confirm this.

# data[].attributes.body
Both Anna and Lucy have a pair of the same shoes with a pattern that matches the shoe-print found at the scene. If the size of the print is compared to Lucy’s and Anna’s shoe-print size, it might be able to confirm whose print it was, unless they wear the same size. It is definitely not any of the other suspects because none of them have the shoe with this pattern on the bottom.
