WASHINGTON ( CNN ) -- The FBI has hit a dead end in its search for a missing 3-year-old Arkansas boy and is asking the public for help . The FBI is hoping the public can help find 3-year-old Dominick Wesley Arceneaux . Dominick Wesley Arceneaux was last seen by an aunt Tuesday afternoon in the front yard of a mobile home in Chidester , in south-central Arkansas , authorities said . In a missing-person alert , the FBI described Dominick as 3 feet tall , weighing 38 pounds , with brown hair and eyes . Kimberly Brunell , a special agent with the FBI in Little Rock , said authorities have made `` an exhaustive search '' of White Oak Lake , close to where the boy was last seen . National Guardsmen have also done a grid search covering a one-mile radius around the home , she said , and are currently expanding it to a two-mile radius . Investigators also have looked at registered sex offenders in the area , Brunell said . They have also found Dominick 's father , who lives in Baton Rouge , Louisiana . `` We have not ruled anyone out at this point , '' she said . The investigation has included looking at patrons of a bar next to the mobile home where Dominick has lived with his mother since December , she said . `` There is not the normal traffic of just neighbors . '' Brunell said investigators have run down every lead and are looking for new ones , including `` suspicious vehicles , suspicious persons ... anyone who might have a nugget that might lead us on our way to finding out what happened to him . '' Anyone with more information is asked to call an FBI hot line , 1-800-CALL-FBI ( 1-800-225-5324 ) .
