The Ouachita County Sheriff says authorities are now leaning  toward the possibility that a missing three-year-old boy was kidnapped from his Chidester home Tuesday afternoon.

Arkansas State Police issued a Morgan Nick Amber Alert late Tuesday for Dominick Wesley Arceneaux.

He was last seen wearing blue jean shorts with red stitching. He is approximately three-feet tall, with brown eyes and short brown hair.

For nearly six hours Wednesday, the Game and Fish dive team searched the shoreline of White Oak Lake.  Arceneaux was last seen behind his family's mobile home, which is only 50 feet away from the lake.

Sheriff David Norwood say he was playing with the family dog and his wheelbarrow around two o'clock Tuesday afternoon.  He went inside to remove his shoes and five minutes later, his mother and aunt, who were inside the home, heard silence. They went outside and discovered the boy had vanished.

Norwood says authorities are considering three possibilities: the boy fell in the lake, he wandered off and got lost in the woods, or he was kidnapped. However, Norwood says they don't have any evidence to support any of those theories. He says they are leaning toward the possibility Arceneaux was kidnapped because they haven't found any sign of the boy.

Dozens of searchers who combed the woods couldn't find any sign of the boy. Divers also turned up nothing. There is a bar next door to Arceneaux's home, however it was closed when he vanished and no one was there, authorities say.

"We're pretty confident he's not in the area," Norwood said.  "We searched the water line and we're pretty confident he's not in the areas he might have fallen in."

Deputies have interviewed at least 25 people so far, including all sex offenders in a 25-mile radius.

They've also cleared family members at this point of any suspicions.

The boy's mother has been questioned throughout this process, but she is not a person of interest at this time. Authorities say they will interview certain individuals again on Thursday but they have no specific person of interest.

Investigators have searched a 40 to 50-acre area and they will expand that range and retrace their steps beginning Thursday. They are also considering bringing in State Police search dogs to assist. Representatives from the National Center for Missing and Exploited Children are also heading to the area to help.

If you have seen this boy you are asked to call the Arkansas State Police or the Ouachita County Sheriff's Department.
