Kimrey was taken into custody at the Onslow County Sheriff's Office on Friday.
Federal Bureau of Investigation spokeswoman Shelley Lynch confirmed in an email Saturday that 32-year-old Earl Kimrey was living with 3-year-old Mariah Woods and her family when she disappeared almost a week ago. Kimrey is Mariah's mother's boyfriend, according to multiple media reports.
She was allegedly abducted from a home on the 2400 block of Dawson Cabin Road in Jacksonville, according to an Amber Alert issued Monday, when she was reported missing.
Kimrey is charged with concealing of death, obstruction of justice, burglary, theft, and possessing stolen property.
Kimrey is now being held at the Onslow County Detention Center under a $1,010,000 bond.
In a news release Saturday, the sheriff's office also stated that it believes the toddler is dead.
In all, 730 volunteers joined law enforcement personnel in the search on Friday. Her mother told investigators that she last saw Mariah late Sunday night.
The FBI says they have been sending "items of interest" to their lab in Quantico, Virginia, for priority testing in the case.

The statement says investigators think the girl is dead, but didn't say how she might have been killed. "Someone just walked right up in there, grabbed the 3-year-old out of the bed and she didn't cry, she didn't scream?" "Four people in the house, two adults and two kids, someone just comes up and snatches the baby and walks out?" Woods said her boyfriend, Kimrey, also checked on her around midnight. Once they realized she was missing, the couple said they called authorities.
At a Thursday press conference, Federal Bureau of Investigation officials said that "items of interest" were taken to Quantico for testing that could "lead us to Mariah", but did not elaborate on what the items were, or where they were located. Please just bring her back safe and sound - she's my baby, she's my everything'.
Residents were moved to action following Woods' public appeals for help in the search for her "very sweet, loving girl" with blue eyes and long brown hair. They said no information is too small or insignificant when looking for the missing child.
