You've been called to the scene of a murder. The lock on the victim's apartment door was broken, likely by a crowbar found in the doorway. The victim was found lying face down on the floor with a bullet in his back. Based on the condition of the apartment, it appears a struggle occurred between the victim and the murderer. There are several drops of blood located in the nearby kitchen, as well as a broken glass on the floor. Assuming this situation occurred in the late 1800s, which relatively new type of evidence would most likely be used to identify the killer? DNA samples taken from the hair and blood found on the floor Motives of possible suspects based on information from the victim's wife Fingerprints found on the crowbar and on the glass Information obtained after examining the bullet under a comparison microscope

Part 2: Crime Scene Analysis: Case #1: A stolen car was found on the side of the road with an empty bottle of Sprite. Detectives were able to collect enough DNA from the saliva left on the top of the bottle to create a DNA fingerprint. Below are the DNA fingerprints from the crime scene and two suspects who were seen near the abandoned car. 1. Based on these banding patterns, who stole the car? (1 mark, T) 2. How do you know? Justify your answer by explaining how you interpreted the gels (2 marks, T)

At 1:00 a.m., someone breaks a window in the back of a store and robs the safe. On the way out, the thief is cut on a piece of broken glass. A forensic team collects and tests a sample of blood left behind by the thief. It is O-. The police bring in a suspect with a cut forearm who was arrested just three blocks from the store. The person resembles someone seen leaving the store at the time of the robbery. A sample of the suspect's blood is taken and tested for blood type. Once the suspect's blood is mixed with anti-A serum, it is immediately clear that the suspect is not the person who was cut on the broken glass in the store. How did the test indicate that fact?
