Part X: Crime Scene Investigation

This was the final stage in our study of forensics, seaming together all of the components of forensics we learned about into one investigation and analysis. In this, I worked in a group of seven at Scene 3, using ten pieces of evidence found at a crime scene in order to analyze and correctly solve the crime.
Scene 3 Background: This took place at a break-in of a residence.

Exhibit 1: The first piece of evidence was a black, size 8 shoe with a 3.25 inch heel (8.5 centimeters).

Exhibit 2: The second piece was a note torn apart, saying "Someone please help me," which matched up with the writing of Tyrese Jefferson.

Exhibit 2A: This was another torn apart note, this one matching up with Smokey Johnson's handwriting and saying, "You will never find her."

Exhibit 3A: Ulnar loop fingerprints were found that match up with Tyrese Jefferson and Sandra O'Connor.
Exhibit 3: This was a plain whorl print that matched with Smokey Johnson.

Exhibit 4: A gold earring was found that's post was slightly bent.

Exhibit 5: This was a small square of green nylon.

Exhibit 6: After performing tests on it, this substance was discovered to be iodine.

Exhibit 7: This was a footprint found in dirt that was 12 inches long, 4.5 inches wide, and seemed to be a skating shoe. The size also indicates it was likely a male's print.

Exhibit 8: This was a patch of blood that was found to be type A+, which is the same as Tyrese Jefferson's, Courtney Smith's, and Jeb Sampson's.

Exhibit 9: Exhibit nine was many strands of short hair, which, under the inspection of a microscope, were found to belong to Tyson, a dog.

Exhibit 10: The final piece of evidence was that of a latent fingerprint that had to be lifted using graphite. Even though this was somewhat difficult to see, it was most likely an ulnar loop.

Analysis:
After studying and analyzing the found evidence my group and I came up with a solid theory on what happened at this crime scene:
As was stated in her profile, Tyrese Jefferson was a counselor; Smokey Johnson was one of her patients with mental problems. Unfortunately, he became obsessed with her to the point of stalking her; the footprint in the dirt was from him looking into her house from under a window, which also had his fingerprint on it. She finally gets a restraining order on Smokey, which enrages him. One night, Tyrese came home from a party; after taking off her earrings and a shoe, she sees a shady figure approaching her home. She tries the phone to call for help, but realizes the line has been cut and quickly scribbles a note saying, "Someone please help me." Smokey forcibly enters her home and assaults her, bludgeoning her on the head, which is where the splotch of blood came from, ripping off a piece of green nylon from her dress in the struggle, and knocking her earring off the table and bending its post. Smokey writes the note, gloating that, "You will never find her,", and since she is unconscious from being hit on the head, takes her from her home.

Additional Information:
1. Tyrese's fingerprint was left on her earring.
2. Smokey left Tyrese's iodine behind, which she needs for her thyroid glands to produce hormones for her metabolism, since, as said in her profile, she has thyroid problems.
3. The dog hair left behind in Tyrese's home was from when she watched Tyson for a neighbor earlier that day.
