Camm, a former Indiana State Police trooper, is charged with killing his wife, Kimberly, and his two children, Bradley and Jill, in their Georgetown, Ind., house in September 2000.

Terry Laber took the stand for the fourth straight day, but now the prosecution was asking the questions.

NewsChannel 32's Abby Miller reported that lead Prosecutor Stan Faith called into question Laber's techniques, testing and his results.

Camm's defense lawyer felt that the jury was not impressed.

"We're saving a lot of money on paper and pens this morning. The jury isn't writing much of this cross-examination down," defense attorney Mike McDaniel said.

Miller reported that Faith attacked Laber's conclusions that blood found on Camm's T-shirt and shoes got there by his walking around the bodies of his wife and children in the garge.

"He can't find anyplace where there's a track in the blood that would indicate that that's what caused the projected blood," Faith said. "I hope they think that the man simply throws out a concept and just sees where it falls and that's all that happens there. It's not worth anything."

Faith also raised the question of bias, saying that Laber and his partner received copies of a timeline (pictured, right) made by members of David Camm's extended family.

The timeline gives Camm's version of events the night the murders. Faith argued that Laber tailored his findings to match the family's timeline, Miller reported.

"They made it very clear to him what they wanted him to find, and that is bias in itself," Faith said. "That creates a 'I won't be hired anymore if you don't find it the way I find want it to be found.'"

"I think they understand about bias, and I think they understand what's important in these cases and I have not heard Mr. Laber say anything or shade anything that he could not substantiate," McDaniel said.

Laber's testimony is all that stands between David Camm and the witness box, Miller reported.

Laber's testimony had taken longer than anticipated, which means that Camm could take the stand as early as Wednesday, but most likely on Thursday.

McDaniel said that his client is ready to go.

"You get mentally geared up. It's like getting ready to play a World Series game and getting rained out. You've got all the adrenaline and no place to go, so I think he's ready to testify," McDaniel said.
