when was the first recorded criminal case using forensic science to convict some one for murder.?

You'd probably have to go back to the 14th or 15th Century for this one; though 14th or 15th Century forensic science was crude at best, scientists at that time were were very meticulous investigators.\n\nOTBPOC

It is, of course, impossible to know how many innocent people are convicted, because we cannot know the absolute truth in all cases. However, we do know how many people have been convicted and eventually exonerated. A detailed study in 2004 by the University of Michigan examined exonerations for major crimes between 1989, the year DNA evidence came into its own, and 2003. They found 328 exonerations, almost all for rape or murder. To put this in persepctive, there were 8,990 convictions for murder and 10,980 convictions for rape in 2002, among more than a million convictions for serious offenses in general.

I think it depends on several different factors. Your previous criminal history, how close you came to murdering someone, how heinous the crime is, who the victim was (an infant would probably be punished more harshly than an adult), the state you committed the crime in, etc.\n\nI have seen a lot of cases where the defendant gets between 12 - 15 years with no previous criminal record.

Wikipedia is your friend.  The link is to the article on forensics.\n\nCheck out the external links at the bottom of the article, too.

Wikipedia's page on the topic states:\nIts use has been recorded as early as ancient Egyptian, Greek and Roman civilizations.

It depends on the intent when the crime was committed. Ex. Murder one is premeditated with malicious intent.

It goes back to the Salem witch trials in the late 1600's. People were charged, convicted and executed on the flimsiness of evidence or no evidence at all. Sometimes all that was need was for someone to accused them.

In 1867, the German chemist August Wilhelm von Hofmann discovered formaldehyde, whose preservative properties were soon discovered and which became the foundation for modern methods of embalming.

I expect from the moment there was a USA.  The death penalty was always there and would have been part of the history the early settlers brought to the US.  It was probably also in effect in some way among aboriginal populations.  As long as there have been people there has been a death penalty in one form or another.  \n\nThe first established death penalty laws date as far back as the Eighteenth Century B.C. in the Code of King Hammaurabi of Babylon, which codified the death penalty for 25 different crimes.  Here are a few interesting links.

You might try a website called Homicide in Chicago 1870-1930.  It features a Crime Commission Report for 1915.  It seems to be a very large and complex research site and features among much more, an Interactive Database where you may be able to pin this information down. http://homicide.northwestern.edu/pubs/ccreport/

No it won't.  People have been very interested in the case from the onset.  Very intelligent people have been trying to figure that one out.  So far all that they have come up with is speculation.\n\nIt is important to keep in mind that during that time a lot of murders were never solved due to limited investigatory tools.  Jack the Ripper just exploited that fact in his horrific murder spree.

First answer -- You're a moron\n\n-----------------------------------------------------------\n\nThis is a very difficult question to answer, since there are probably not records that old. We do know that there were criminals and courts in ancients times (Egypt, Greece, and Rome, among others). For example, we know that Socrates was convicted and sentenced to death (or exile, he chose suicide) (for corrupting youth) by Hemlock in 399 BC. Now, this wasn't the first or the first recorded, but it will give you an idea of how far back this goes!

Yes, I think about how many people over the past 5 years who have been released from prison because DNA proved them innocent.  I bet there are hundreds of people in time, maybe even executed, for crimes they did not commit.

Check out the web links below. I think the answers to your questions are there.\n\nForensic science technicians investigate crimes by collecting and analyzing physical evidence. Often, they specialize in areas such as DNA analysis or firearm examination, performing tests on weapons or on substances such as fiber, glass, hair, tissue, and body fluids to determine their significance to the investigation. Proper collection and storage methods are important to protect the evidence. Forensic science technicians also prepare reports to document their findings and the laboratory techniques used, and they may provide information and expert opinion to investigators. When criminal cases come to trial, forensic science technicians often give testimony, as expert witnesses, on specific laboratory findings by identifying and classifying substances, materials, and other evidence collected at the scene of a crime. Some forensic science technicians work closely with other experts or technicians. For example, a forensic science technician may consult either a medical expert about the exact time and cause of a death or a technician who specializes in DNA typing in hopes of matching a DNA type to a suspect.
