The FBI is now working with state and local authorities in order to locate the missing girl, according to ABC affiliate WCTI. "We are not releasing it to the public at this point", Miller said.
Onslow County Sheriff Hans J. Miller told Fox News there appeared to be no sign of a break-in or unlawful entry at Woods' home.
Ms Woods said her daughter was a "little angel" with a talkative personality. "Just bring her home please safe and sound". She said when she checked on the little girl at 6:30 a.m., she was nowhere to be found.
The FBI is now assisting in the search for a missing 3-year-old girl in North Carolina after an AMBER Alert was issued Monday morning.
According to the alert, Woods is a white female about 2 feet 9 inches tall, weighing 30 pounds. Even with the aid of a helicopter and drones, authorities didn't find anything to lead them to Mariah.
"It is extraordinarily rare for a stranger abduction, someone to come into a residence simply for the sole motivation of taking an infant child", said retired FBI agent Greg Baker, who is not involved in the investigation into Mariah's disappearance. She said her boyfriend saw the child about midnight when she got up and he told her to go back to bed.
The girl's grandmother was the one who initially discovered that Mariah was not in her room when she went to check in on her in the morning.

Law enforcement officials also searched the home and the family's auto for evidence.
"I didn't think it was real", Woods told Grace.
Woods also revealed that her daughter has to wear orthopedic leg braces and worries that she won't be able to walk without them.
Mariah's father, Alex Woods, who does not live with her mother, has expressed skepticism about the circumstances surrounding his daughter's disappearance.
The FBI had released three photos earlier Wednesday of a blonde girl being held by a woman with dark hair at a Walmart in Morehead City, N.C. The bureau later clarified in a news release that the woman and child in the photos have nothing to do with the case of missing Mariah Woods.
The girl's two older brothers were in the house when Mariah disappeared. They said no information is too small or insignificant when looking for the missing child.
Kristy Woods on Tuesday issued an emotional plea for the girl's return.
In addition to the prayers Wednesday night, the Onslow County Sheriffs Office, as well as the Federal Bureau of Investigation, made a statement asking for assistance from citizens.
