So glad you mentioned this. It makes me question if he may be mistaken about what day he saw a baby at 4 AM. He has the temperature wrong and also said he "waited about a week" to report it. Weather Underground says at 4 am on 10/4, the temperature was 57.9. (Yeah, too cold for a baby but not 45)
MT said "[It was] 4 o'clock in the morning, 45 degrees, the baby don't have a blanket or coat or nothing, and this guy's walking down the street," MT said. "I thought it was kind of weird."
MT claimed the infant -- who was only wearing a diaper -- resembled Lisa and said that he would recognize the man if he saw him again.
He said he waited about a week to report the sighting to police because he did not immediately make the connection to the girl's disappearance.
I am not saying that he is lying, just that this is another case of eye witnesses sometimes not being 100% reliable. People make mistakes.
