The mother of missing baby Lisa Irwin is preparing to be charged in connection with her baby's disappearance, according to a family member who says she thinks that an arrest is "inevitable."

Ashley Irwin, the aunt of the missing 10-month-old, said in an exclusive interview with ABC News that she believes police are spending more time focusing on the family -- in particular baby Lisa's mother Deborah Bradley -- than on finding 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."

Baby Lisa has not been seen since last Tuesday, when her father Jeremy Irwin said he returned to their Kansas, City, Mo., home from working an overnight shift as an electrician and found his daughter's crib empty, the front door to the house unlocked, a window open and the family's three cell phones gone.

Bradley says that she was the last to see the baby when she put her to bed.

When asked if she has any doubt that Bradley or her brother Jeremy Irwin had anything to do with baby Lisa's disappearance, Ashley Irwin confirmed that she thinks there is no way that they could be involved.

"Anybody who spends any time with them, you know it's not true -- she's genuine -- she loves that child. It's her baby … she would never anything to hurt her," she said.

"She doesn't care what happens to her, she doesn't care what people say about her, she doesn't care what people think about her, all she cares about it getting Lisa home," Ashley, the only person speaking publicly for the family, told ABC News.

Kansas City police have been suspicious of the parents' story since their initial questioning; Bradley said that police accused her of having done something to her child, and also accused her of failing a polygraph test. Police said they could not comment on this claim, but said Bradley is "free to say whatever she wants."

The relationship between police and the parents soured last week when police said the couple had stopped cooperating -- but by Saturday Jeremy and Deborah were again meeting with investigators.

In a separate development, Clay County grand jury subpoenas have begun arriving at least four local Kansas City network affiliate television stations who did interviewing in their coverage of the case. Investigators are demanding unedited "footage of any interviews… given by neighbors, family or friends of the family..."

Sources say that the police may want to compare the footage for inconsistent statements from witnesses or anyone else interviewed surrounded the baby's disappearance.

So far police have only hit dead ends in their investigations, but have said that in the week since baby Lisa disappeared over 250 tips have come in.

"We're chasing down the ones we can but still unfortunately nothing has really come from them," said Capt. Steve Young of the Kansas City Police Department.

Neighbors have said that they have been questioned about a homeless man seen in the neighborhood roughly two weeks ago, according to The Associated Press.

New developments arrived Monday as crime scene investigators ventured into an overgrown drainage ditch behind the family home.

Police insist they are leaving no stone unturned. They have also staged a re-creation of a hypothetical kidnapping scenario with an intruder breaking in through the family's window.
