Eric Piedmont Polygraph
When asked if he killed Anna, he responded no but the line went up from about 7 to 13, at a slope of 1.2. This could figure that he lied and actually did kill Anna Garcia -
Dominique Hall Polygraph
When Dominique was asked if she killed Anna, she answered with no but the line spiked up from about 4 to 15 at a slope of 0.73. Although Dominique's slope was lower than Eric's, she could still be a suspect. -

Eric Piedmont Fingerprint
The fingerprint at the scene found on the note had a unique loop found at the bottom of the fingerprint. Eric Piedmont's fingerprint also had a unique loop on the bottom suggesting that Eric touched that note whether it was at the scene or when he gave it to Anna Garcia. -
Anna Garcia Fingerprint
The fingerprint found on the flask at the scene had a very circular whorl right at the center that kind of looked like a ring. Anna Garcia's fingerprint also had a circular whorl at the center that looked like the one at the crime scene. This suggests that Anna Garcia was working on something in the lab and was using the flask. -
Eric Piedmont Hair Samples
From the hair sample found at the crime scene, the closest look-alike is Eric Piedmont's. Both have a couple of darker hairs, and mostly light hairs, all brown, and around the same width. A close second would probably be Anna's but Anna's hair is a lot darker and wider. -
Digital Evidence
As we can see from Anna's social media story, Dominique Hall and Anna were in study hall together 17 hours before her death. It also seemed that Dominique disliked Anna which could be evidence for Dominique. We can also see from Anna and Eric's texts that they had a bad relationship. They were ignoring each other's texts and they didn't seem happy in their relationship -
Blood Testing
The crime scene sample 2 tested positive because the cotton swab turned pink which shows a chemical reaction. From just this test, it’s not 100% real blood but it's most likely real blood. -
Blood Typing
When Anti A serum was added to both crime scene blood samples, it changed so that means the blood at the scene was blood type A. When Anti A was added to the suspect's blood, only three of them were type A, Anna, Eric, and Dominique. It makes the most sense for this blood to be Anna's because she would be bleeding from her death and it matches the blood type. -
Blood Spatter
Anna Garcia could have been bleeding from her head from accidentally banging her head on the table due to her migraine. According to the best fit line, one of the blood droplets found on the ground dropped from a height of 200 cm and had a diameter of 10 mm. The blood fell onto the floor which is a smooth surface so the bloodstain formed was round-shaped.
