Question

data and analysis:
place a check mark in the boxes where clumping/coagulation occurs.
place an x in the box if no clumping/coagulation occurs.

conclusion:
based on the data above, what can you gather about the samples
sent to your lab?

Explanation:

To determine the blood type of the victim, we analyze the clumping (check mark) or no clumping (X) in each serum:

• Anti - A Serum: X (no clumping), so no A antigens.
• Anti - B Serum: X (no clumping), so no B antigens.
• Anti - Rh Serum: Check mark (clumping), so Rh - positive.

A person with no A or B antigens and Rh - positive has blood type O+.

For the samples:

• Suspect #1 (A+) has the same blood type as the Crime Scene (A+), suggesting a possible match.
• Suspect #2 (B - ) and #3 (B - ) don't match the Crime Scene (A+).
• The Weapon has B+ blood, different from the Crime Scene (A+).
• The Victim has O+ blood.

Answer:

• Victim's Blood Type: O+
• Suspect #1's blood type (A+) matches the Crime Scene's blood type (A+), while Suspect #2, Suspect #3, and the Weapon's blood types do not match the Crime Scene. The Victim has O+ blood.
