Question

Upon arriving at a crime scene in 1950, you find dried blood throughout the room. There are three suspects in custody, each of whom has a different blood type. Which scientist's contribution to the field of forensics will you likely rely on to crack the case?

A. Francis Galton
B. Leone Lattes
C. Mathieu Orfila
D. Hsi Duan Yu

Answer 1

Leone Lattes developed the method to determine blood type from dried bloodstains, which would be crucial in a 1950s crime scene for narrowing down suspects.

Step-by-step explanation:

Upon arriving at a crime scene in 1950 and finding dried blood throughout the room, the contribution from Leone Lattes, who developed the method to determine blood type from dried bloodstains, will be the most relied upon. This discovery was fundamental in the field of forensic science, allowing investigators to use blood type to help narrow down suspects. Although DNA analysis had not been developed at that time, analyzing the blood types of the three suspects would give investigators important information to possibly link or exclude a suspect from the crime. By analyzing the dried blood at the crime scene and comparing it to the blood types of the three suspects, Lattes' technique could help identify which suspect left the blood evidence.
