LEBANON, Ind. (WHAS11) -- A new development in the third murder trial for an Indiana man accused of killing his wife and two children.
A forensic biologist told jurors Thursday there's a 50 percent error rate in deciding whether the blood stains on David Camm's T-shirt and shoes were caused by gunshot spatter or contact.
Camm claims it was contact, but the prosecution says it was spatter.
The biologist also said he doesn't believe proper testing was done after those murders 13 years ago.
