"That should raise all the red flags that it raises in my head to anyone who's out there really trying to do an investigation that includes a hunt for Lisa, and hopefully an alive and well Lisa," he said.
Mike Thompson, the witness who claims he saw a man carrying a baby on the side of the road around 4 a.m. the night Lisa disappeared told ABC News police questioned him again on Monday.
"Yesterday they showed me a paper with six pictures on it," Thompson said. "And I picked out the man they had been showing pictures of."
The man in the photograph has been questioned by the police several times, but the other witnesses, a couple who live three houses down from the Irwin house, said the photo did not match the man they say they saw with a baby the night Lisa disappeared.
"No, I don't recognize him," the woman said when shown the photo. "He was tall and slender and, as far as his head, we thought he was bald."
Baby Lisa has been missing since the night of Oct. 3 and an anonymous benefactor is offering a $100,000 reward for her safe return or the conviction of whoever took the little girl.
