I don't think so. It may take more than 7 years (the statute of limitations for other crimes) for someone to confess the lied or reverse their testimony.
I think this is why a lot of lawyers are taught that even eye witness testimony is not 100% reliable.
Example in this case.
Darin says he saw the necklace embedded in her wound.
Nurse Judy says she removed necklace from patient, doesn't elaborate as to embedded or not but that it wasn't difficult to remove, required no special skills.
At time shortly after funeral when I talked to Mama Darlie she told me Dr. had said they had to remove necklace from her wound when she talked to him after Darlie came out of surgery.
Darin is not an expert and his opinion of what he saw cannot be impeached unless he reverses his testimony.
Nurse Judy cannot be charged with perjury unless she reverses her testimony or another 2 witnesses testifies they saw Dr. or someone else besides Nurse Judy remove necklace. Without 2 it is a matter of he said she said.
Mama Darlie did not tape conversation with Dr. after surgery so she cannot prove he said what she says he said.
Dr doesn't testify to anything more than the necklace had to be removed in order to do surgery. BTW they always remove your jewelry prior to any surgery, no metal that is removable is allowed in a surgical setting anyway.
Another example of eye witness testimony being not 100% reliable because they are not an expert.
A plane had to do a crash landing because of engine failure. The plane ended up near a Taco Bell.
A plane passenger told the news reporter that the pilot handled the situation very well.
If he had died in a crash he would not have been able to render his opinion which might have been different.
What is not handling the situation well- the pilot running thru the aisle and screaming we are all dead I'm bailing out I have a parachute forget the rest of you.
The FFA will investigate even if every passenger says our pilot was GREAT.
None of them are experts and if they are they didn't have access to all the facts while sitting in the plane as a passenger. Even if all the passengers aboard were experienced pilots, flight engineers, etc. I'm sure at least one of them would have wished they landed closer to the McDonald's as his stomach won't allow him to eat mexican food.
Any LE or legal minds correct me if I'm wrong about perjury or eyewitness testimony.
