NEW YORK -LRB- CNN -RRB- -- Two-year-old Tangena Hussain vanished three months ago in the Detroit suburb of Hamtramck , Michigan , and police say the trail has gone cold . Tangena Hussain , 2 , has been missing since October 2 and police in Michigan are asking for the public 's help . Tangena 's mother called police on the evening of October 2 , 2008 , to report her daughter missing after frantically searching the area where she was last seen . The child 's mother , Nilufa Begum , told police she had left the girl in the care of her boyfriend , Jamrul Hussain . Although Tangena and Hussain have the same last name , he is not her father . Begum told investigators her daughter was with Hussain all day while she worked at the Northland Mall . Hussain said he stopped at a gas station with Tangena while on the way to the mall to pick up Begum . They stopped at about 9 p.m. to buy gum and juice , he said . Hussain told police he left Tangena in the car for only a few moments and when he returned , the little girl was gone . He did not call police and did not conduct a search , but instead drove to the mall and picked up Begum , investigators said . When she saw Tangena was not with Hussain , Begum asked him where she was . His response was cryptic , she told police . He said he would take her to the place where her daughter was . Begum became alarmed as Hussain drove to a gas station where , he said , Tangena disappeared . They searched for Tangena together , while Begum called the police to report her daughter missing . A surveillance camera shows the boyfriend , Hussain , going into the gas station 's store , police said . On the video , he makes some purchases and leaves within a few minutes . But there is no video of the area where Hussain parked his car , nor any video that could show whether the little girl had been there or how she might have disappeared . Police have not named a person of interest in the toddler 's disappearance . When the media picked up the story , a teenager came forward , saying she recognized Hussain as the man who allegedly attacked her . During the investigation , police discovered that the young accuser , then 15 , had been Hussain 's prior girlfriend . Hussain , 24 , was arrested and charged with two counts of having sex with a minor . He is free on bail while awaiting trial . `` My client is innocent of the charges . He did not have sex with a minor child , '' said Hussain 's lawyer , Shawn Patrick Smith . Tangena 's parents said they just want answers . Her father , Mohammad Ahmed , lives in New York and added $ 5,000 to an existing Crimestopper 's reward of $ 1,000 . `` We are praying that someone knows something that can help us find my daughter , '' Ahmed said . `` How can a child disappear without someone seeing something ? Something does n't fit about -LSB- Hussain 's -RSB- story . '' When questioned , Begun told police only she and Hussain saw Tangena in the week leading up to her October 2 disappearance . A Michigan Amber Alert was issued for Tangena at 5 a.m. the morning after she disappeared . But in the months since , police have hit a dead end . Police and family members are turning to the public for help .
