During the search of the warehouse on December 27, 2003, Detective Dodge Hendee experienced an ah-hah moment. He saw concrete mix powder on the trailer in the shape of circles, a pitcher, and the anchor that Scott said he made at home fitting perfectly into the pitcher. From this, Hendee concluded that Scott made additional anchors that were used to weigh Laci down. In fact, he was so sure about it that he conducted 22 searches of the Bay for those anchors, calling in the most sophisticated side sonar equipment in the US and the most expert FBI dive team, in addition to using the resources of several other agencies in the area.
So what fizzled? Well, the anchor didn't fit perfectly into the pitcher after all, and a concrete expert said the anchor Scott had was not made in that pitcher. Hendee reluctantly almost admitted that he was fooled into thinking that there were actually circles in the concrete mix powder because he mistakenly thought the anchor had been made in the pitcher.
GERAGOS: At the time you thought Ah-hah, I've got some evidence, because the pitcher fits in there, right?
GERAGOS: All right. And that was part of the, it kind of led you to see those circles on the trailer, too, didn't it?
GERAGOS: I mean, you thought,
JUDGE: Wait, wait, wait. One at a time. Sustained. Argumentative.
GERAGOS: Okay. Well, your idea was that this, the anchor, was made in this, the pitcher?
HENDEE: That's what we thought.
GERAGOS: And then from there you extrapolated that the pitcher was on the trailer, and therefore, if it was in four locations, there must have been four of these, right?
HENDEE: We felt that was a possibility.
GERAGOS: Okay. You thought it was more than a possibility; you searched the Bay 22 times looking for these, right?
GERAGOS: Okay. And it turns out at the end of the day the pitcher never made it, right?
He was more forthright about admitting he was mistaken about the anchor being a perfect fit for the pitcher.
GERAGOS: Okay. And as it was on the trailer, he was taking this item, the concrete, right?
HENDEE: Yes, sir.
GERAGOS: The anchor, and he was holding it like this?
GERAGOS: As it was inside, right?
GERAGOS: And it was his and your opinion that it was a perfect fit?
HENDEE: Mistakenly so.
GERAGOS: Tell the jury why that was mistakenly so.
HENDEE: Because it was looked at by a concrete expert who determined that this mold was not made in this pitcher.
Here are 3 pictures of the trailer before the MPD marked the "circles" with evidence markers, followed by a series of pictures taken by John and Robyn Ungari at their local Home Depot. Seems like concrete mix bags tend to spread a lot of dust around, some even could be called "circles."
