Debbie Bradley isn't talking to investigators and only she can provide needed answers in the investigation into her missing daughter, Kansas City police said Friday.
Police issued the statement just ahead of next week's one-year anniversary of the disappearance of then 10-month-old Lisa Irwin from her Northland home.
It is the most direct comment that police have made about Bradley since the initial days when the baby was reported missing on Oct. 4.
Bradley and the child's father, Jeremy Irwin, maintain their daughter was kidnapped from her crib and they had nothing to do with her disappearance.
"I just want her back," Irwin told reporters Friday afternoon.
Detectives have exhausted all leads provided by the child's family and their attorneys, according to the statement.
"The leads were of no benefit to the investigation," according to the statement from Capt. Steve Young. "While communication with the family has been ongoing, police have not had the opportunity to sit down one-on-one with Lisa's mother, Deborah Bradley. As the only adult in the home at the time of the baby's disappearance, police continue to have questions to which only she can provide answers."
Irwin had a succinct reply when asked about the police statement. (warning: strong language)
"I think it's bullshit to be honest with you," Irwin said.
In an interview with Reuters this week, John Picerno, the Kansas City attorney for the parents, said Irwin and Bradley are giving "100 percent and complete" cooperation to police.
"There is no question she was kidnapped," Picerno said. "If there was any foul play involving Deborah or Jeremy we would (have) heard about it by now."
Young said police "are not putting any label" on Bradley when asked by KCTV5 whether she is a person of interest.
"We still have questions that need answered as the news release states," he said.
Neighbors say Bradley heads out every day with a fresh stack of fliers and talks to people regularly. Lisa's picture dots trees and is on family vehicle. One neighbor said Bradley personally tends a makeshift remembrance for her daughter outside the home.
The family and neighbors said they hope the one-year anniversary will lead to needed answers. A vigil will be held next week in the neighborhood.
"I talk to Deborah all the time. Under the circumstances, she is doing as well as can be expected," Deborah Delorenzo said. "She lives with constant hope and prayer for her child as we all do in this neighborhood."
Police and FBI agents have investigated 1,667 tips since Oct. 4. Officers are working about a dozen tips now.
"Five hundred of the total tips have been infant sightings across the United States and internationally," according to the statement. "Police thank the FBI agents and detectives at other law enforcement agencies - domestically and overseas - who investigated each of these sightings. None of them was determined to be Lisa Irwin."
A Kansas City police detective and FBI agent try to work the case every day.
"They are still looking for quality tips. They have gone back over nearly 100 previously closed leads, re-interviewing those involved to ensure they haven't missed anything," according to the statement. "Dozens more detectives stand at the ready to investigate a break in the case."
Detectives have reviewed the entire case file with the National Center for Missing and Exploited Children in Alexandra, VA. Their experts continue to offer their assistance.
"Detectives remain hopeful for quality tips that will lead them to Lisa," the news release concludes. "However, several tips stemming from social media and online rumors have been reported, detracting from detectives' ability to work legitimate case leads."
Police ask anyone "with substantial knowledge of what happened to Lisa Irwin" to call the TIPS Hotline at 816-474-TIPS.
"Because the Lisa Irwin disappearance remains an active, open investigation, Kansas City police will not grant any further interviews," according to the news release.
