Data of Crime Scene Investigation

On our table my group found the following pieces of evidence:

Exh. 1A: Piece of hair
Exh. 2A: Second piece of hair
Exh. 3A: Ripped up note
Exh. 4A: Blood
Exh. 5A: Fingerprint on glass surface
Exh. 6A: Mike Kelly's wallet

We then proceeded to use the techniques we learned to analyze the data. This is what we discovered:

• 1A: Piece of hair: This hair we identified as black male using microscopy.
• 2A: Second piece of hair: We identified this sample as cat hair using the same method as above.
• 3A: Ripped up note: There was some pieces of a ripped up note. Once we put them together, we found out that it said, "I have your diamond ring." We then compared the handwriting to the suspects' handwriting and found that it matched up to Ralph Johnson.
• 4A: Blood: We used a blood typing kit to identify the blood we found. It turned out to be Type A, which suspects' Jenny Cho and Ralph Johnson had.
• 
• 5A: Fingerprint on glass surface: We identified this to be an ulnar loop, which Mike Kelly had.
• 6A: Mike Kelly's Wallet: Had no money, but had an ID.
