LOS ANGELES, CA (Catholic Online) - "Detectives are looking at every possible angle," Capt. Steve Young of the Kansas City Police Department says. "All we know is that there should've been a 10-month-old in that house and we are doing everything we can to find the kid."

FBI agents with dogs searched the family's home, a light-green ranch-style home in an older neighborhood along a winding street near hills. An FBI spokeswoman has declined to discuss why the agents entered the home or what they found. Officers scoured the neighborhood and knocked on doors in their hunt for the missing child.

"We've received several tips and we certainly encourage people to call, but we also need information that is specific to the case," Young told msnbc.com.

Little Lisa was last seen when her mother put her to bed at about 10:30 p.m. Monday. The search began about 4 a.m. Tuesday when her father returned home from work and discovered her missing.

Police have discounted the theory that Lisa could have crawled away. They are currently investigating the possibility that an intruder entered the home through a window and snatched her.

Young said the parents have been cooperative. "As you can imagine nobody knows more about what's going on in that house than the parents do," he said.

There is currently no reason to suspect Lisa's parents were involved in her disappearance but added, "At this point we have next to nothing and are not ruling anything out."

A daylong search that included more than 100 officers, FBI agents, and police dogs yielded no clues. Interviews with the parents also didn't provide any clues, Young said.

Nothing has been discovered around the house or in a search of the two cars in the family's driveway either.

The parents are currently staying with relatives away from their northern Kansas City home. Police said they were aware of the parents' whereabouts, but would not disclose their location.

Lisa Irwin's grandparents and neighbors have told television reporters that they have not heard from the couple since they left police questioning. The grandparents told the TV station that they were caring for the couple's two other children.

Lisa has blue eyes and blond hair. She is 30 inches tall and weighs between 26 and 30 pounds. Police say she has two bottom teeth, a small bug bite under her left ear and a beauty mark on her right thigh. She was wearing purple shorts and a purple shirt with white kittens on it.
