LEBANON, Ind. (AP) _ A judge overseeing a triple-murder trial has banned testimony that a former Indiana state trooper molested his 5-year-old daughter, calling the claim speculation without enough evidence to support it.
 
Monday's ruling will prevent prosecutors from offering testimony that was key to David Camm's second conviction in the September 2000 slayings of his wife, son and daughter.
The Indiana Supreme Court overturned Camm's second murder conviction in 2009, largely citing unsupported arguments that Jill Cam had been molested and  that David Camm had killed his family to keep it secret. His first conviction in the killings was also thrown out.
 
Lawyers argued Monday over the defense motion to exclude the testimony largely while jurors were out of the courtroom.
 
Camm's third trial is being held about 25 miles northwest of Indianapolis.
