(CBS/AP) KANSAS CITY, Mo. - Law enforcement officials launched a new round of searches Monday for missing Kansas City baby Lisa Irwin after the her mother went on national television and admitted she was drunk at the time of the infant's disappearance.
Deborah Bradley said in an interview with NBC's "Today" show, that she believes she will be arrested in the disappearance of her daughter, who was 10 months old when she was reported missing early Oct. 4.
Bradley said she bought boxed wine and consumed "enough to be drunk" that night, but denied she did anything to hurt Lisa.
"No, no ... I don't think alcohol changes a person enough to do something like that," she said.
Not long after the interview aired, local and federal authorities began fresh searches for the girl, including bringing tracking dogs into the family's home and draining a nearby creek.
FBI spokeswoman Bridget Patton said agents brought the dogs into the house after Lisa's parents, Bradley and Jeremy Irwin, consented to the search. Dogs were also used to search a next-door neighbors' house.
Earlier in the day, FBI agents used the dogs outside Irwin's parents' home, where he and Bradley have been staying. There were no immediate reports of what police may have found at either property. On Sunday, military police from the Missouri National Guard joined FBI agents and officers from several police and sheriff's departments in searching a large wooded area near the family's home.
Jeremy Irwin has told authorities that he arrived home from a night shift to discover the front door unlocked, the house lights blazing, a window tampered with and the baby gone. Bradley and their two sons were asleep elsewhere in the home.
Authorities have already searched the family's neighborhood, nearby wooded areas, a landfill and abandoned homes. Police have said they have no suspects or major leads.
