Lesson Connections:
1.
Which suspect had the same blood type as the blood on the door frame?
Suspect 2
2.
Is this match enough to convict the suspect of the crime? Why or why not?
Yes, as it could very well be theirs
3.
What are some struggles forensic scientists may have when collecting and testing blood evidence?
The blood could’ve been mixed with other blood/elements or could have very well been tampered with
4.
Explain what would occur if blood type A was mixed with Anti-A serum.
They would not produce
5.
What components of blood are in the crime scene sample? Which components are absent?
