( CNN ) -- The parents of a missing 10-month-old Missouri girl late Thursday indicated they are cooperating with detectives , counter to what police said earlier in the evening , a relative said . A woman who identified herself as Ashley Irwin , sister of Jeremy Irwin , read a statement on behalf of her brother and Deborah Bradley , parents of missing infant Lisa Irwin . `` We have never stopped cooperating with the police . We 've been cooperative from day one and we continue to assist the police with the investigation , '' the statement said . `` The main goal has always been to find Lisa and bring her home . That remains the sole focus of the parents . '' Ashley Irwin said the parents , who will release another statement Friday , wanted to thank police and the community for their efforts and prayers . Kansas City , Missouri , police Capt . Steve Young had said earlier that the pair had stopped assisting police in the investigation . `` I do n't have to illustrate how that affects the investigation , '' Young said of the development . `` It speaks for itself . '' Young , who said `` our door is always open '' to the parents , told reporters that there are no suspects in the case . Earlier Thursday , the parents told reporters about how they discovered Lisa to be missing . `` She 's everything , '' Bradley said of Lisa . `` She 's our little girl . She 's completed our family , and she means everything to my boys . We need her home . I ca n't be without her . '' Irwin urged anyone with information to call police . `` Anything , even the smallest information , could help lead to her return , '' he said . Lisa Irwin was last seen around 10:30 p.m. Monday , asleep in her crib , police said . They were called to the home at about 4 a.m. Tuesday . `` It appears the suspect entered/exited through a bedroom window , '' authorities said in a statement . `` Evidence at the scene leads police to believe the child has been abducted . '' Jeremy Irwin told reporters that he found Lisa missing when he got home from work . `` The front door was unlocked , '' he said Thursday . `` Most of the lights were on in the house , and the window in front was open -- all very unusual . '' The couple claimed three cell phones were missing at their home , Young said , but the information has not turned up anything . Police have said the parents are not considered suspects in Lisa 's disappearance . Young on Wednesday told reporters the family had been cooperative , but `` everything is still on the table . We have n't ruled anything out . '' He said then that investigators `` really have n't developed any good , hard information that we can go forward with . '' Nearly 50 tips have been received through a hotline , he said , but not all of them have been pursued , as some of them have been vague -- a person calling to report a child seat seen in a car , for instance . `` I know everybody 's hearts are in the right place , but that 's not anything we can do anything with , '' Young said . Police have conducted more than 300 `` knock-and-talks '' and searches of residences in the area , and more than 300 officers were searching for Lisa . There have been three searches of a wooded area near the family 's home , he said . `` I promise you , if there 's anything we think we can be doing , we 've probably done it two or three times already , '' Young said . An Amber Alert was issued for Lisa early Tuesday but has been canceled . `` Although the investigation and search for Lisa Irwin continue , an active Amber Alert is no longer necessary in this case , '' police said . However , Lisa is still considered missing and endangered , according to authorities . Lisa is described as 30 inches tall with blue eyes and blond hair , police said . She weighs between 26 and 30 pounds . She was last seen wearing purple shorts and a purple shirt with white kittens on it . She has two bottom teeth , a small bug bite under her left ear and a `` beauty mark '' on her right outer thigh . She currently has a cold with a cough , police said .
