After examining the fingerprints found on the overturned table, we matched the ridges to the fingerprints of Anna Garcia and all the suspects, which resulted in Alex Garcia’s fingerprint matching to the crime scene fingerprints. We also identified the substance of the pills found on the floor next to the ground. After testing several possible substances, aspirin matched the crime scene substance, therefore the pills Anna took were Aspirin (also the toxicology report revealed she has trace amounts of aspirin in her body).

  • Dna Fingerprinting Lab Report

This is because identical twins have the same DNA because they come from the same egg. If a suspect’s DNA matched that of the one being tested, and they had an identical twin, a farther investigation would need to be done.
