Kansas City , Missouri ( CNN ) -- The family of a missing Missouri baby continued to make news Friday , cutting ties with its attorney hours after canceling a police interview with the girl 's two half-brothers . Cyndy Short , the attorney who had been speaking for the family of 11-month-old Lisa Irwin , is no longer working with the family , her Kansas City , Missouri , law firm announced Friday in a statement . There was no immediate indication as to who , if anyone , will represent the family instead . Meanwhile , Kansas City Police Captain Steve Young said late Thursday that the Irwin family 's lawyer -- at that point , presumed to be Short -- had canceled a police interview with the girl 's two older brothers . The boys , ages 8 and 6 , were in the family 's Kansas City home when the girl was reported missing on October 4 . They were previously interviewed just after she disappeared , both for less than an hour , Kansas City police Capt . Steve Young said . The `` nonconfrontational '' re-interview planned for Friday would have been conducted by a child services specialist without a police officer in the room , according to Young . `` ( It 's ) not an interrogation , '' he said . `` They are kids , after all . '' It was unclear whether the boys ' interviews will be rescheduled . Authorities have also said they are seeking tests on the boys , in order to eliminate them from all the DNA found in the home during a search . Police have said the infant 's parents , Jeremy Irwin and Deborah Bradley , will not submit to separate interviews . But Short , speaking earlier as the couple 's attorney , disputed that account . `` Being questioned separately is not the issue , '' Short said . She said the couple has been cooperative and has been interviewed separately as well as together . They do n't mind being interviewed separately as long as the detectives are fair , open-minded and nonaccusatory , she said . Lisa was reported missing about 4 a.m. October 4 , after her father arrived home from work to find the door unlocked , the lights on and a window tampered with . The girl 's mother said she last saw Lisa at 6:40 p.m. the previous day . A cadaver dog searching the family 's Kansas City home indicated a positive `` hit '' for the scent of a body , police said . On that information , Short said law enforcement typically begins such investigations inside the home , and then , if warranted , the inquiry moves outside the family . `` We do n't know exactly what happened here , so we need to keep broadening the investigation , '' she said . CNN 's Jim Spellman and Bill Kirkos contributed to this report .
