LEBANON, Ind. (AP) _ A former Indiana State Police analyst says tests on the fingernails of the slain wife of a former trooper did not reveal DNA from a man convicted of killing her and her two children.
 
The Courier Journal reports Lynn Scamahorn's testimony during the third murder trial of David Camm appeared to contradict defense claims that Kim Camm struggled with Charles Boney before she was killed. Police found one of her fingernails at the scene, indicating a possible struggle.
 
Camm is accused of fatally shooting her and their children, 7-year-old Brad and 5-year-old Jill, in the garage of their home in Floyd County in September 2000.
 
Two prior convictions were overturned on appeal. The case has been moved to central Indiana because of publicity over the case.
