Missouri National Guard officials joined the search for a Kansas City baby on Sunday as the girl's mother told Fox News she was drunk when the 10-month-old disappeared.
Deborah Bradley, the mother of missing girl 10-month-old Lisa Irwin, told Fox News on Sunday that she was drunk when the girl disappeared. She admitted having "several glasses" of wine -- perhaps as many as 10 -- with a neighbor prior to the girl's disappearance on Oct. 4.
Bradley also admitted she last saw Lisa Irwin at 6:40 p.m. local time, not 10:30 p.m. as she had originally told investigators.
Bradley said it was possible she blacked out after drinking, but denied that anything could have happened to Lisa while she was drunk. She said she drank about twice a week when her children were asleep and denied having a drinking problem.
"I don't see the problem with me having grownup time," she told Fox News' Megyn Kelly.
About 25 members of the guard's 139th Military Police Company based in nearby Harrisonville, FBI agents and officers from several police and sheriff's departments from nearby communities in Missouri and Kansas split up into several groups and scoured a large wooded area west of the family's home.
Authorities and FBI officials launched new searches for the girl on Monday, including the drainage of a nearby creek. Investigators also brought tracking dogs to the yard of the home where the girl's parents have been staying since she was reported missing.
The girl's parents said Lisa Irwin disappeared from her crib sometime overnight. Previous searches have included the family's neighborhood, nearby wooded areas, a landfill and abandoned homes. Police have said that so far there are no suspects or major leads.
Nearly 100 people were involved in the search Sunday, said Bridget Patton, a spokeswoman for the FBI, which has been assisting the Kansas City Police Department.
"We put a call out and got a huge response," Patton said.
Gov. Jay Nixon ordered the guard to help in the search for one day. Guard spokeswoman Rachel Knight said it was unclear if the guard would be involved after Sunday.
Knight said the guard members and the other law enforcement groups were going over a large wooded area that had been searched before to make sure nothing was missed. Several guard members dressed in camouflage and carrying long sticks could be seen heading off to a wooded section in mid-afternoon.
Knight said they would be scouring the area, searching "with additional manpower and fresh eyes to see if there's anything they missed ... They're crawling through the area, going over it with a fine-toothed comb."
Kansas City police spokesman Steve Young said the extra help from law enforcement and the guard was appreciated.
"They volunteered their help, and we accepted," Young said.
Young said a man found a backpack containing diapers and baby wipes near a vacant home close to the Irwin's residence on Saturday. Diapers were also found in a wooded area across the street from the house. According to at least one local report, the diapers were soiled.
Young said that the diapers appeared to have been there for some time, adding that it's not unusual to find objects like backpacks and diapers in abandoned houses.
A $100,000 reward was offered on Friday by an anonymous donor for the child's safe return or information leading to a conviction of anyone involved in her disappearance.
A group of about six area residents who said they were "concerned citizens" -- but did not want to be identified -- also walked around the family's neighborhood Sunday, saying they were looking for any information they could find about the baby's disappearance.
