KANSAS CITY, Mo. (AP) - Authorities searching for a 10-month-old girl looked Tuesday inside a cistern under the deck of a vacant Kansas City home just five blocks from where the girl went missing a week ago.

The Kansas City Star reported a firefighter said he felt something after being lowered about 11 a.m. into the receptacle designed to hold rainwater and other liquid. A different person was lowered down before noon.

Two large trucks with suction equipment arrived at the home to drain water from the cistern, and a Kansas City Power & Light truck also showed up at the scene.

A neighbor said the single-story house had been abandoned for about four years.

Lisa Irwin's parents, Jeremy Irwin and Deborah Bradley, reported their daughter 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.

The search of the property came a day after a court ordered Kansas City television stations to submit all footage of interviews with the girl's family and friends.

Investigators said Tuesday they have no suspects in the case.

But Bradley has said police told her she failed a lie detector test. She has denied having anything to do with her daughter's disappearance.

Grand jury subpoenas from Clay County Circuit Court were sent late Monday to at least four network affiliates in Kansas City, according to their websites. The subpoenas asked the television stations to submit "all footage, including raw footage of any interviews or statements given by neighbors, family or friends of the family, regarding missing baby, Lisa Irwin."

The subpoenas, which were requested by the Clay County prosecutor's office, said at least two of the stations were told to appear with the footage in court on Oct. 18.

Jim Roberts, a spokesman for the prosecutor's office, said the
subpoenas were needed to prevent broadcasters from destroying video they might otherwise discard because it could be needed later. The subpoenas were issued by a sitting grand jury, not on called
specifically for this case.

Detectives and crime scene investigators were at the family's home Monday for more than two hours scouring areas of the backyard and poking through shrubbery and grass in the back of the house and in neighbors' yards. Police earlier in the investigation searched a landfill, nearby woods, an industrial park and sewers in their effort to follow up on more than 300 tips.

"Our detectives are doing everything possible you would expect them to do in this case," said Capt. Steve Young, spokesman for the Kansas City Police Department. He declined to comment on the subpoenas.

Bryan McGruder, vice president for news at WDAF, said the station would provide all footage it had aired about the case. But he said the station would not hand over any raw footage because workers "routinely recycle what we use."

R. Michael Cassidy, a professor at Boston College Law School, said there could be several reasons for seeking the footage. He said investigators may want the footage to find inconsistencies in parents' accounts of the events surrounding their daughter's disappearance.

"It could mean that they have one or both of the parents as suspects, and they are developing evidence of everything they saidin the past and prior to the arrest," Cassidy said Tuesday. "To show that someone's story has shifted over time can also be very damning."

Police may also want the footage to review "the landscape around the house," shortly after the disappearance was reported.

"It could be that these visuals of the immediate area are important," Cassidy said.
