( CNN ) -- Authorities have obtained a search warrant for the home where a missing 11-month-old Missouri girl was reportedly last seen , Kansas City police said Tuesday . The warrant allows investigators to comb the house in the coming days and also bars the family of Lisa Irwin from returning home . A patrol car has been posted outside . Lisa was reported missing at 4 a.m. October 4 , after Lisa 's father , Jeremy Irwin , came home from work to find the door unlocked , lights on and a window that had been tampered with . Lisa 's mother , Deborah Bradley , said she last saw Lisa at 6:40 p.m. the night before . The developments came as a potentially promising lead in the case turned out to be a false alarm . The Riley County Police Department received a report Tuesday that `` Baby Lisa '' may have been sighted in Manhattan , Kansas -- more 100 miles west of Kansas City . A baby with two `` suspicious '' looking women were reportedly seen in a local deli . Authorities were able to `` confirm that the child seen was not the child missing from Kansas City , '' police said . Earlier in the week , Bradley said in an NBC interview she was drunk the night the infant disappeared and that she had last seen the baby about four hours earlier than initially reported . Bradley told NBC she is afraid she will be arrested . Police have accused her of killing Lisa , she said , and told her that she failed a lie detector test . `` I was the last one with her , '' a tearful Bradley said in the interview . `` And from judging on how the questioning went , that 's kind of a fear that I have . And the main fear with that is , if they arrest me , people are going to stop looking for her . And then I 'll never see her again , and I 'll never know what happened . '' Asked how much she had been drinking that night , Bradley said , `` enough to be drunk . '' But she rejected the notion that she could have harmed her daughter while under the influence of alcohol . `` No , no , no , '' she told NBC . `` And if I thought there was a chance , I 'd say it . No . No . I do n't think alcohol changes a person enough to do something like that . '' Asked whether he had questions about Bradley , Jeremy Irwin told NBC , `` No . There 's no question to be had there . I know who she is . I know the kind of mother she is . '' Irwin said it 's possible someone could have entered the house without Bradley hearing , as the couple 's bedroom is on the opposite corner of the house from Lisa 's room and Bradley sleeps with a fan at high speed . Lisa is described as being 30 inches tall with blue eyes and blond hair , according to police . She weighs between 26 and 30 pounds and was last seen wearing purple shorts and a purple shirt with white kittens on it . The missing girl has two bottom teeth and a `` beauty mark '' on her right outer thigh , police said . At the time of her disappearance , she had a cold with a cough . CNN 's Bill Kirkos contributed to this report .
