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.
It is the most direct comment that police have made about Bradley since the initial days when baby Lisa Irwin went missing nearly a year ago.
Police issued the statement just ahead of next week's one-year anniversary of the then 10-month-old baby.
Detectives have exhausted leads, including those provided by Bradley and Lisa's father, Jeremy Irwin.
"While communication with the family has been ongoing, police have not had the opportunity to sit down one-on-one to speak with Lisa's mother, Deborah Bradley," according to the statement. "As the only adult in the home at the time of the disappearance, police continue to have questions to which only she can provide answers."
Reuters reported this week that John Picerno, the Kansas City attorney for Lisa's parents, said that Bradley and Irwin are giving "100 percent and complete" cooperation to police.
