Sgt. Stacey Graves of the Kansas City Police Department told FoxNews.com that, "We have heard nothing from detectives to lead us to believe an arrest is imminent."

Ashley Irwin, the aunt of the missing girl, told ABC News early on Tuesday that the arrest of the child's mother, Deborah Bradley, was "inevitable." Irwin said the police had been focusing on the family rather than more "viable" suspects.

"It's what the police do," Ashley Irwin said. "They don't have any leads so they just have to pin it on somebody."

Graves, however, has told FoxNews.com that police have "no suspects" and "are continuing the investigation until Lisa is found."

"We are still actively following up on leads and tips as they come in," she said.

Lisa was reportedly last seen last week on Monday around 10:30 p.m. when her mother Deborah Bradley put her to bed in a crib, police said.

Lisa's parents reported her missing last Tuesday morning after her father, electrician Jeremy Irwin, returned home from work. Her parents said someone must have crept into their home while the child's mother and brothers slept and snatched the baby girl.

Meanwhile, Kansas City television stations were subpoenaed Monday to submit footage of interviews with friends and family of a missing 10-month-old girl.

Police have said they have no suspects in the case. But neighbors say they have been questioned about a homeless man seen in the neighborhood about two weeks ago.
