Mystery Man Brings New Questions in Case of Missing Baby Lisa Irwin

Surveillance footage from a gas station near the Kansas City home where baby Lisa Irwin disappeared shows a man exiting a wooded area shortly before the baby was reported missing.

The video, first reported by ABC News, shows a man dressed in white leaving the leafy area at 2:30 a.m. local time the night the baby was last seen. The footage may support the claim by the girl's parents, Deborah Bradley and Jeremy Irwin, that the 10-month-old was abducted from their home.  

Discovery of the video follows statements by at least three witnesses who reported seeing a man with a baby in that area on the night Lisa disappeared.

Deborah Bradley told authorities she last saw the girl in her crib on the night of Oct. 3. She was reported missing more than nine hours later -- around 4:00 a.m. -- when her father returned home from work and noticed she was gone.

On Friday, a police affidavit revealed that an FBI cadaver dog picked up the scent of a human body on the floor of Bradley's bedroom.

Witness Mike Thompson told ABC's "Good Morning America" that he was heading home on his motorcycle around 4:00 a.m. Oct. 4 when he noticed the man, who was dressed in a T-shirt, on a street near the child's home.

"[It was] 4 o'clock in the morning, 45 degrees, the baby don't have a blanket or coat or nothin', and this guy's walking down the street," Thompson said. "I thought it was kind of weird."

Two other witnesses, who were not named, said they encountered a similar scene a few hours earlier.

"It was shocking because I couldn't imagine anybody outside walking with their baby in the cold like that with no clothes on," the female witness told ABC.

Former FBI agent Brad Garrett told the network that the timeline did not make sense.

"Are you going to logically abduct a child, let's say in the midnight area, then two to four hours later, you are spotted in the proximity of the neighborhood," he said. "I mean, that doesn't make any sense. It could be true, of course, but the logic of abducting a child is so you can take the child to some other location."

The baby's parents continue to be the subject of intense media and police scrutiny over their actions the night she disappeared.

Bradley admitted in several interviews Monday she drank between 5 and 10 glasses of wine Oct. 3, the night Lisa was last seen. She told Fox News in an interview that it was possible she blacked out after drinking but denied that anything could have happened to her daughter while she was drunk.

She also admitted she last saw her baby at 6:40 p.m. local time, not 10:30 p.m., as she had originally told investigators.
