Investigators continue intensive search for Lisa Irwin in and around her home

KANSAS CITY, Mo. - Lisa Irwin’s parents were at their house Wednesday as investigators continue to search the area for clues into the girl’s disappearance. They addressed the public for the first time at a 2 p.m. news conference .

Lisa was discovered missing around 4 a.m. Tuesday when her father returned to their home in the 3600 block of North Lister Avenue from work to find her not in her crib.

NBC Action News reporter Chris Hernandez reported Lisa’s parents arrived to their home sometime around noon Wednesday, met with family and neighbors at a nearby home and then went with investigators into their back yard.

Earlier, NBC Action News reporter Sloane Heller reports Lisa’s grandparents were watching the couple’s other children at a neighbor's house and had not been able to reach them since Lisa's parents had left an interview with police Tuesday night.

At a news conference Wednesday morning, Capt. Steve Young, with the Kansas City Police Department, said Lisa’s parents, who are not considered suspects in their 10-month-old daughter's disappearance, were interviewed by investigators until around 10:30 p.m. Tuesday.

Young confirmed the couple left the police station Tuesday night and said police are aware of Lisa's parent's whereabouts, but would not disclose their location. Lisa's grandparents and other family members have spoken off-camera, but have declined to speak on-camera until given a green light by Lisa's father.

Investigators in protective clothing entered Lisa's home Wednesday morning. Search dogs were also canvassing the scene.

Authorities on scene say it's standard procedure to bring the dogs into the search for a missing child. The dogs are being used to pick up Lisa’s scents. She disappeared from her home in the 3600 block of North Lister Avenue Monday night.

The protective plastic suits are being worn to hide investigators' scents from the dogs.

The FBI brought out several bags of evidence about 15 minutes after Lisa’s parents accompanied investigators into the backyard. Shortly after that, the parents came out with some personal belongings.

Authorities have still not developed a suspect in Lisa’s apparent abduction, but say they are still using all available resources in the search to find her.

Young said search dogs are going through the woods near Lisa Irwin’s home for a second and third time and officers are canvassing her Northland neighborhood and knocking on doors in hopes of finding the missing girl.

Young said the search has not expanded beyond the area canvassed Tuesday, but local and federal authorities continue their efforts in bringing Lisa home.

Around 3:30 p.m. Wednesday, law enforcement officers were seen riding ATVs in a wooded area southeast of the Irwin home.

Earlier Wednesday, in an interview with NBC Action News Reporter Lindsay Shively on NBC Action News Today, Young said no stones are being left unturned in the search of Lisa.

“Since we don’t have much to go on, we are definitely not ruling anything out,” he said.

“The parents were cooperative,” Young said, “but I think at that point, everybody had been at it since about 4 in the morning and it was a reasonable time to stop.”

In his 9 a.m. update, Young said other family members have been interviewed, along with others in the community, and hundreds of tips have come in, but nothing has turned out any hard evidence or information on a possible suspect.
