Breeann?s Parents Fail Lie Detector Test; Training Wheels Found

A pair of training wheels similar to those that were on Breeann Rodriguez's bicycle were found two and a half miles from her house, Senath, Mo., police chief Omar Karnes said Friday. The wheels are "items of interest," he said.

Breeann's father, Edgar Rodriguez, told FBI investigators he was "100 percent" sure the wheels were from Breeann's bike. He explained to them that he had adjusted them for her in a distinct way to "manipulate the training wheels and bike to lower it for her height," CNN reported.

The bicycle has not yet been found.

In another twist to the case, Rodriguez and his wife, Claudia Ramos, both failed lie detector tests.

Rodriguez spoke with Nancy Grace about the lie detector failure.

"I don't know, honestly, honestly. When my wife went in there first to do the polygraph and she failed it, I mean, of course as a father when someone tells you they failed a polygraph, it automatically raises doubt."

He expressed skepticism of the test and results.

"I don't know. To be completely honest with you, I don't believe we really did fail it. It may be some kind of tool they use to squeeze every bit of information out of us. I don't really know. But they said we did fail it."

Breeann, 3, has been missing since Saturday. She was riding her bike with her brother outside of their house. He went inside for a drink of water and when he came back outside she was gone.

Breeann is Hispanic, 34 inches tall, weighs about 30 pounds, and has black hair and brown eyes. She was last seen wearing a pink top and pink and purple pants. Police are asking people with information to call 866-371-TIPS.
