(AP) -- Update: Oct. 11 at 2:50 p.m.:

Police say a search of a cistern under a deck at a vacant Kansas City home turned up no signs of a 10-month-old girl who has been missing for a week.

Kansas City firefighters took turns Tuesday being lowered into a 40-foot cistern at a home five blocks from where Lisa Irwin went missing Oct. 4. But officials say the three-hour search came up empty.

Lisa's parents reported her missing after her father returned home from work around 4 a.m. last Tuesday. Her parents said someone must have crept into their home while the child's mother and brothers slept and snatched the girl.

Police say they have no suspects and have found no evidence despite an intense hunt by hundreds of investigators from local, state and federal agencies.
