Debbie's parents flew to San Antonio to spend time with Lars.

to support him in their shared grief.

He could hardly talk.

He seemed extremely remorseful.

He apologized profusely for it and said it was just an accident, it was dark.

Some people might be really angry, but you didn't go down that road.

We did not go down that road.

We supported him.

Lars Itzo admitted he fatally shot his wife, Debbie, but said it was a terrible accident.

From the very beginning, he cooperated with police, answered every question, no lawyer present.

Then, about eight hours after that first conversation about the shooting, Lars headed back to the station and sat down for a polygraph test.

But the polygraph indicated Lars was deceptive in some of his answers.

His brother and sister said it was perfectly understandable.

Maybe so.

But his performance on the polygraph was enough for detectives to grill him relentlessly.
