Fingerprinting, using a dog’s sense of smell, and taking blood, crime investigators have used these techniques for crime solving.

The first autopsy was done in 44 BC by a doctor trying the figure the actual cause of death of Julius Caesar.

A lot of the techniques that were used in the early 1900’s are still used today, but they have advanced because of how technologically advanced society has become.

One of techniques that are still used today, but has progressed through the years is using microscopes to look at hair samples, dust, and dirt, closely. This technique was first developed in the early 1900’s and was a way to look more in depth into clues.

Microscopes are used for looking at skin and blood cells more closely and making the small cells much bigger and more visible.

For the future use of microscopes like a 3D microscope, it makes the cells are visible and easier to see. They also would help improve with surgery procedures.

Dogs have also played an important role in solving crimes. They were used in the beginning of the 1900’s and even now to sniff out criminals and sniff clues leading to the criminal’s whereabouts. Using dogs with their keen sense of smell were and are now a big part of solving crimes today.

Using dogs are now a useful tool in helping police track down criminals, if they are hiding or trying to find evidence in a crime scene.

For the future use of dogs used in military and police combat are robotic dogs that will be used for special operations on tough situations or dangerous landscapes.

Another technique is fingerprinting, which is used today. In the early nineteen hundreds police officers used fingerprinting to identify criminals and they use the same technique, just in an advanced state. In the 1900’s police would swipe a certain kind of powder and on a criminal’s finger and stamp it on a piece of paper with the criminal’s identification.

Today, fingerprinting is a helpful tool in finding criminals, but only the dumb ones, because if criminals are smart enough they would wear gloves to hide their fingerprints.

The future of fingerprinting is called Lab-on-a-chip, where is takes the jobs of the scientists doing all the work to machines, removing the DNA, from the fingerprint. This invention would help with it taking half the time, it would for scientists to do it by hand and it would use pumps and tubes to take the job of the scientists.
