In one of the first recorded uses of fingerprints to solve a crime, Faulds used fingerprints to eliminate an innocent suspect and indicate a perpetrator in a Tokyo burglary. ]]> 2021-09-16 14:27:28 UTC https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746148231 mateoflo229 https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746158200 In 1920  Charles E.

However this technique was not fully accepted, and consequently was not often used until the early 2000s, when the FBI started using the technique as an improvement over existing techniques. Analysis of DNA with the STR method, in combination with a technique called PCR, allows much smaller amount of DNA to be identified, and can be used on DNA that has been partially damaged.³]]> 2021-09-16 14:43:59 UTC https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746199902 mateoflo229 https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746205982 There is new studies where text messages are used to examine the criminals motives much like examination of forged documents. ]]> 2021-09-16 14:46:00 UTC https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746205982 mateoflo229 https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746209392 There is also the use of new computer programs to identify where a criminal has committed crimes to try and identify where the criminals lives ]]> 2021-09-16 14:47:09 UTC https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746209392 mateoflo229 https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746212318 Lastly there is the use of computer programs to analyze a crime scene and recreate the crime to show any clues we may have missed ]]> 2021-09-16 14:48:08 UTC https://padlet.com/mateoflo229/rua60w4n2uthqcm1/wish/1746212318
