Summary
The Oklahoma State Bureau of Investigation (OSBI) uses a likelihood ratio threshold in forensic DNA analysis to assess evidence strength. DNA profiles not meeting criteria are ineligible for CODIS entry, often due to sample quality or quantity. In criminal investigations, victim DNA is typically not entered into CODIS, which is reserved for offenders and crime scene evidence. If a defendant is already in CODIS, it does not affect the eligibility of new profiles for entry.Full Conversation
I was wondering what the treshhold is for the likelyhood ratio that used by the osbi
Hi Chris! The Oklahoma State Bureau of Investigation (OSBI) generally uses a likelihood ratio threshold in forensic DNA analysis to determine the strength of the evidence. This threshold can vary based on the specific case and the context, but it typically needs to be significantly high to support evidentiary conclusions.
What specific legal concern do you have regarding this threshold?
just curious.
Got it, Chris! If you have any other questions or need more detailed legal information, feel free to ask. I'm here to help!
what does it mean if a DNA lab report done by the osbi states that "no profiles identified were eligible for entry into codis
Case Rating: *
It means that the DNA profiles obtained from the evidence did not meet the criteria for submission to the Combined DNA Index System (CODIS). This could be due to a variety of reasons, such as the quality or quantity of the DNA sample not being sufficient for CODIS standards. If you have further questions, feel free to ask!
in the event that the defendant is already in codis and the other * samples tested were that of the alleged victim and a sample from the alleged victims aborted baby fetus, on this same report,could that change what is meant by that statement
Case Rating: *
The presence of the defendant's profile in CODIS and the testing of samples from the victim and the fetus would not change the statement regarding eligibility for CODIS entry. The report likely indicates that the new DNA profiles did not meet the criteria for CODIS entry, regardless of existing entries.
Would you like more information on DNA evidence criteria?
in a criminal investigation do they enter the victims DNA into codis
Case Rating: *
In a criminal investigation, the victim's DNA is generally not entered into CODIS. CODIS is primarily used for storing DNA profiles of convicted offenders, arrestees, and forensic evidence from crime scenes. The victim's DNA is usually used for comparison purposes only.
