32-year-old Earl Kimrey was taken into custody by investigators at the Onslow County Sheriff's Office Friday.
A missing 3-year-old North Carolina girl is believed to be dead and her mother's boyfriend has been arrested in connection to the disappearance that prompted an Amber Alert earlier this week.
Arrest warrants obtained by CBS North Carolina report Kimrey obstructed justice by, "removing Mariah Woods' body from the scene of her death and did hide Mariah Woods' death and body, knowing that Mariah Woods died from unnatural causes".
The girl's mother made tearful pleas for her daughter in the days after she disappeared sometime between Sunday night and Monday morning.
The Onslow County Sheriff's Office said in a statement that Kimrey, of Jacksonville, North Carolina, was arrested late Friday on charges that include concealing a death and obstruction of justice. He was being held in the Onslow County Detention Center under a $1 million bond, a news release stated.
Additional charges could be filed against Kimrey as the investigation continues.

Investigators posted, "Due to evidence gathered during the course of the investigation, it is believed that Mariah is deceased".
The FBI says more than 700 people came to join in the search for a missing North Carolina child.
The girl is shy and has an orthopedic leg problem, her grandmother said, according to CBS News. Family members said Kimrey lived in the home with Mariah and her mother; photos on Facebook show the pair together with Mariah.
The FBI said it has been sending "items of interest" to its lab in Quantico, Virginia, for priority testing in the case. "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?" he said. Once they realized she was missing, the couple said they called authorities. "She's my baby, she's my everything", said Kristy Woods in a press conference. "Please, bring her back".
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. The missing child's case has shifted to a homicide case.
