If something like a murder occurred though, DNA could wrongly accuse someone. For example if you were an identical twin and you and your twin had the same DNA you could be convicted of their crime. In my article DNA helped scientists link Whale Digestive blobs (Jetsam Ambergris) that is used to make perfume, to which whale was creating it. The sperm whale was confirmed as the originator because the DNA matched -Morgan

They had an idea of who it was, but none of the evidence lead to him. Alec Jeffrey was asked to compare the DNA and possibly relate it to the suspect. He ended up comparing DNA collected at a similar murder case 3 years earlier to the one that just happened. The DNA matched from both cases, and they convicted Colin Pitchfork to both murders, giving him a life sentence. ]]> 2020-03-24 14:59:12 UTC https://padlet.com/jeck1/8m0hed8cwkuu/wish/472903907 https://padlet.com/jeck1/8m0hed8cwkuu/wish/473582259  In 1998, Illinois Governor George Ryan had DNA testing done to death row inmates and found 13 of the 25 could be exonerated by the results. He stopped all executions untill the evidence had been sorted out. Roy Criner from In Texas, was sentenced with circumstantial evidence to 99 years for the rape and murder of a 16 year old girl. MAny years later, he submitted to DNA testing which proved that he could not have been the murderer.  Even though he had been proved inocent, the judge would not set him free untill more evidence wwas found and it later was.

Simpson case, DNA was attempted to be used to find out who murdered Nicole Brown. If the forensic scientists had taken the right steps into finding and collecting evidence, then the case would have been solved. But they didn’t. The lost and contaminated much of the evidence collected, making in unusable. A pro of DNA would be if the correctly collected the blood from the scene then they could match the blood DNA to a person. A con would be if they didn’t collect the blood correctly the could get an alternate DNA linking to a innocent person. Corey

Police developed a male DNA profile from the crime scene evidence, but found no match in state and national databases. In 2016,  Detective Steve Reopelle followed Gary Hartman into a restaurant and Reopelle observed him using a napkin multiple times and also crumpling it . The napkin was collected and got sent to a laboratory and they told the police that the DNA on the napkin matched DNA found at the crime scene. Police took Hartman. into custody. In  this article this DNA from the napkin helped investigators solve a mystery that was unsolved for a while. By a single napkin, the DNA came from Hartmans saliva.  -- Maachah]]> 2020-03-25 02:43:27 UTC https://padlet.com/jeck1/8m0hed8cwkuu/wish/473818706 https://padlet.com/jeck1/8m0hed8cwkuu/wish/474457113 The year after the arrest of a Golden State Killer, criminal investigation had improved to show better results. Many investigators had solved violent crimes, but had lead to dead ends. But some revolutionary new technology was developed by female that had techniques to locate biological parents of adoptees. One woman, Diane Harman Hoog, 78 year-old director of education at DNA Adoption had found a new technique that could identify two bodies, but no one had believed that she can solve two cases. Years later, an innovator, Barbara Rae-Venter, a genetic genealogist uploaded crime scene DNA to GEDMatch. com which resulted in founding a suspect by using family tree and genetic data from cousins. That was how investigators was able to figure out the a former police officer, Joseph DeAngelo was convicted of 26 counts of murder, including kidnapping and scores of rape.]]> 2020-03-25 12:47:07 UTC https://padlet.com/jeck1/8m0hed8cwkuu/wish/474457113 https://padlet.com/jeck1/8m0hed8cwkuu/wish/474529942 In 1982, Police in Victoria, Texas, began to store biological material in a freezer. Hoping that someday this evidence could become useful. In 2011 they began looking  at the frozen materials again. They were able to connect the evidence to almost 80 cold cases, including several sexual assault cases. Since 2011, there have been several instances where DNA evidence from crimes that happened months, years, even decades ago, have been used to help solve the cases. The ability to store DNA in the national database has also lead to perpetrators of crimes being caught who were even suspects at first.

If the police were to give up on the case and never revisit it, Gary Hartman could be murdering more people. -Morgan]]> 2020-03-25 14:56:48 UTC https://padlet.com/jeck1/8m0hed8cwkuu/wish/474718076 krull888 https://padlet.com/jeck1/8m0hed8cwkuu/wish/476328289 Shea in your article I like how they didn´t accused anyone for the murder, they just had an idea on who it was. But then none of the evidence lead to him. DNA in this article was important because they were also to compare a similar case that happened 3 years ago and DNA matched both cases. The DNA matched to Colin Pitchfork and were able to solve the cases by the DNA they collected.- Maachah]]> 2020-03-26 12:17:30 UTC https://padlet.com/jeck1/8m0hed8cwkuu/wish/476328289 https://padlet.com/jeck1/8m0hed8cwkuu/wish/482316591 DNA has revolutionized criminal investigations, with DNA profiling methods becoming the gold standard in forensics since the first case, where the murderer Collin Pitchfork was caught with help from genetic evidence. Profiling has become faster, more sensitive, and more user-friendly over the past 30 years and has become more advanced. The first DNA databases in the US were established in 1998 by the FBI as a part of CODIS. This has helped the DNA database expand with more knowledge and research, as well as collecting more people's DNA that is kept on record, which is used to solve criminal investigations.

This Is because if they had just collected the evidence correctly that mishap would have never happened and it would have been so much quicker. I also think that after this case evidence is treated a lot better so they can prevent that from happening again.
