We just learned about Forensic Entomology, looking at evidence of bugs!
Another part of detective science is Forensic Epidemiology.
This is the science of looking at someone who is sick or injured, making a guess as to why it happened, and then trying to prove that the guess was right or wrong.
A lot of times people get sick or injured, and we think we know what caused it.
If someone has really bad breathing problems, detectives can look around for bad chemicals in the house, and then do some tests to see if that was really what caused their problems or if maybe they were a smoker or something else.
When a person gets into a car crash and then has neck problems, the science of epidemiology helps prove whether or not their neck problems were because of the car crash or if they would have had the same neck problems from something else.
This type of science is very important, because if scientists can prove that something is bad and causes sickness or injury, then things like bad chemicals can be made illegal, cars can be changed to have better safety, medicines and surgeries can be proven to be good or bad.
