( CNN ) -- Orlando 's police chief on Monday named a Florida man as the `` primary suspect '' in the case of the man 's missing ex-fiancee , who has n't been seen since the two appeared on an episode of `` The People 's Court . '' Police Chief Paul Rooney identified Dale Smith Jr. , who relatives say is the father of two of Michelle Parker 's children , as the lone suspect in the case . `` We had to look at every aspect of the case before we could come out publicly and state that Mr. Smith is our primary focus , '' Rooney said at a news conference . `` We will not rest until Michelle is found . '' Although Rooney publicly identified Smith in the case , no charges have been filed . The woman was last seen driving near Orlando on November 17 , shortly after `` The People 's Court '' segment that had been taped months earlier aired . Her last known communication was a brief , seemingly innocuous text message to her brother that same day , according to the official Facebook page devoted to her case . Attempts to reach Smith by phone -- at numbers believed to be his and that of his parents -- and social media -- via Facebook e-mail , on a profile believed to be his -- for comment on Monday 's developments and the case generally have thus far been unsuccessful.‬‪ ‬‪ . He has refused authorities ' offer to take a polygraph test in the case , Rooney told reporters . Parker 's mother , Yvonne Stewart , said in Monday 's news conference that the naming of Smith as a suspect is `` huge . '' She urged him to come forward more earnestly , in hopes that his information will lead to her daughter . `` This is a sad day , really , but I think it was inevitable , '' Stewart said . `` ( Michelle is ) so beautiful , she does n't deserve this . '' Rooney acknowledged that authorities recently searched Smith 's parents ' house , though he did n't `` want to go into evidence that we seized or did n't seize . '' Parker 's black Hummer SUV was found a day after she was last seen , according to the Facebook page . She is described as white , 33 years old , roughly 5 feet 5 inches tall with short dark brown hair . Her sister , Lauren Erickson , earlier told HLN 's Nancy Grace that her sister and Smith met about five years ago . They were estranged , and `` The People 's Court '' episode revolved around their dispute over who 'd get a $ 5,000 engagement ring , with Judge Marilyn Milian eventually suggesting they split the proceeds and stay apart from one another . Erickson said that her sister was devoted to her children , whom she , her mother and the rest of the family have not seen since Parker 's disappearance . `` She would never do anything to leave them . They are her world , '' Erickson said . `` They ` re the reason that she was working two jobs and going to school full time -- so that she could give them a better life . '' On Monday night , brother Dustin Erickson told HLN 's Vinnie Politan that for all the talk about Smith , his main focus is on his sister . He and other family members urged people to continue distributing fliers , spreading the word about Parker and looking for her at every opportunity . `` My biggest thing is that I still need to search for my sister , '' Dustin Erickson said . `` She is still missing and I still need to find her .
