(KANSAS CITY, Missouri) -- The parents of missing toddler Lisa Irwin haven't submitted to an interview with detectives for the last 10 days to answer questions about things "they might only know," police said today.
The 11-month-old girl vanished from her crib Oct. 3. Police have not named any suspects in the girl's disappearance, but the story of mother Deborah Bradley has altered somewhat and she has admitted to being drunk that night, possibly even blacking out.
Kansas City Police Capt. Steve Young expressed some frustration Tuesday with Bradley and the girl's father, Jeremy Irwin.
"The last time that the mom and dad sat down with detectives to answer questions about things they might only know was Oct. 8," Young told ABC News.
"And that time, and previous times, there came a point when Deborah became uncomfortable and stopped the questioning," Young said.
Young conceded that the parents have spoken with detectives since Oct. 8, but only to clarify information about tips that have come in.
"We strongly believe that that parent's cooperation and involvement is critical [in finding Lisa]," Young said.
Police have previously accused the parents of halting their cooperation, although the parents have insisted they continue to answer officers' questions. Tuesday’s comments by police were more specific.
Young also responded to criticism by Joe Tacopina, the high powered defense lawyer who is now representing Bradley and Irwin.
Tacopina told Good Morning America today that the way some of the local authorities conducted themselves in the hours following Lisa's disappearance was "baffling."
"I am aware that he offered some vague criticisms of the police department," Young said. "I think all reasonable people know that are doing things and we know things that are not a matter of public record."
"Should we develop something that we think will benefit the case by making public, by all means we'll be doing that," the captain said. "But to make the assumption that we're putting all our eggs in one basket would be wildly inaccurate."
Young said the police have so far cleared over 550 tips and leads.
