It was not said that he *never* said he danced with her, it was said that he did not say it during the Keene interview and the Redden interview. You can check the media interview that was also submitted in evidence to see if he says he danced with Brenda on there. He *may* have added that story later.
Not much later, ABC news has a Feb 8th story saying Westerfield claimed to have danced with her.
"Westerfield told reporters he left the bar at around 10:30 pm after dancing with Brenda van Dam."
Then FrontPage reports it on the 13th
"There’s more to the Westerfield angle: He saw Mrs. van Dam at the bar earlier in the evening, where, he claims, they danced (which she denies)."
Brenda denied the dancing at the March 13th preliminary hearing
"Did you dance with Mr. Westerfield?" Deputy District Attorney Jeff Dusek asked.
"No," van Dam said.
And she continued to deny it until June 4th when she said:
"I DON'T RECALL.."
