LEBANON, Ind. (AP) _ A defense attorney says a former Indiana State Police trooper charged with killing his wife and two young children won't testify at his trial.

Defense attorney Richard Kammen told reporters after Thursday's court session that he didn't think there was any reason for David Camm to testify.
 
Kammen's comments came after two expert witnesses for the defense testified they believed tunnel vision led investigators to discount evidence of another man's involvement.
 
The defense expects to rest its case Friday _ some seven weeks after testimony in the trial began.
 
Camm is charged with fatally shooting his family in September 2000 at their home in the southern Indiana town of Georgetown, about four months after he resigned from the state police. Camm's two previous convictions were thrown out on appeal.
