No sign of Lisa Irwin 7 days into search

KANSAS CITY, Mo. - Police have not released any information about a potential suspect in the disappearance of 10-month-old Lisa Irwin, but a neighbor, who did not want to appear on camera, said investigators have questioned him about a man who has been seen riding his bike in the neighborhood.

The neighbor said authorities brought a picture of a man to his door and asked him if he had seen him.

He told police that he had seen the man, who he described as in his 20s, riding a bike and carrying a backpack.

The neighbor, who has lived in the neighborhood for 40 years and says he knows all of its residents, said he is sure the man does not live close by and was suspicious of the man even before Lisa disappeared.

Another neighbor, Norval Nichols saw the man who he described as an out-of-work handyman three times during the month of September.  He said he saw the man first at a park, then twice on the block.

During the first encounter with the man at the park three weeks ago, he spoke with Nichols. "He said, 'do you know any place I could move in with or live with somebody?. I said, 'no,'" Nichols said.

Nichols said the man pulled out a large knife and started peeling an orange.

"I didn't really like him, so I got up back to my truck," Nichols said.

This past weekend Nichols was questioned by police. 

LOOKING FOR LISA: Pictures of Lisa Irwin

Police have said they are continuing to look into every lead, but have not commented on the man and say they have no suspects or significant updates to provide in the case.

Hundreds of investigators with the Kansas City Police Department and FBI have followed hundreds of leads, but seven days into a search that started Tuesday, Oct 4, when Lisa was reported missing when her father returned home from work, there has been no sign of the girl.

Lisa’s father, Jeremy Irwin, said the front door was unlocked, lights were on in the home and a front window appeared damaged when he got home and realized his daughter was missing.

Investigators were back at her Lister Avenue home over the weekend, recreating the alleged abduction scene , trying to crawl through a window that has been called a possible way someone could have gotten in the house.

They went through the house videotaping what they saw.

Meanwhile across the state line, Lisa's aunt tried to get the attention of race fans from across the country, in town at the Kansas Speedway in Kansas City, Kan., selling t-shirts and handing out missing posters.

Lisa's parents, Deborah Bradley and Jeremy Irwin, again declined to talk to our reporters this weekend, but did grant a network interview where they say the baby monitor is always on .

They also talked about finding the computer room window damaged that is being investigated as a possible point of entry into their house.

Police say while the active search for Lisa has ceased, investigators continue to follow leads into her disappearance.

If you think you might have any information about Lisa's disappearance or her current whereabouts, you are urged to call the TIPS Hotline at (816) 474-TIPS.
