The little girl is missing from her home on Sleepy Hollow Drive off Murchison Road in Fayetteville.
Crime scene technicians worked well past dark Wednesday night collecting evidence inside the mobile home where Davis disappeared.
Earlier in the day investigators were back at the mobile home park after a soiled child's blanket believed to be the little girl's was discovered in a trash can outside neighbor Andrea Moore's home.
"You know just this whole time I was thinking to myself oh my God, at least they could tell me that this baby is not in my trash can," she said. "Once they came and got it, I realized there was no child in that trash can."
Moore says officers told her they found feces on the blanket, on the railing and porch of the child's home.
Police say Moore is not a suspect.
Police were called to the little girl's home just before 7 a.m. Tuesday. The girl's mother, Antwanette Davis, told investigators she put her daughter on the couch around 5:30 a.m. and noticed her missing an hour or so later.
"From the information we gained during the night, something went wrong," said Fayetteville Police spokesperson Theresa Chance.
Police say they aren't buying that story.
"There is definitely something that's not right about that situation foul play is suspected," Chance said.
Investigators suspect the 5-year-old was taken out of the home sometime late Monday night, but aren't saying why or by whom.
"We are searching for her and hoping she is still alive, but we don't know at this point," Chance said.
Police searched the area Tuesday around the mobile home on the ground and in air. They used dogs to scour the neighborhood and were also checking all vehicles leaving the area.
"Everybody is just wondering what happened to her, so am I because I have a 5-year-old as well," neighbor Gail Lindsay said. "So I know I would be losing my mind right now."
Authorities took the child's mother, her boyfriend and her sister in for questioning. They say there has been domestic and custody issues in the past.
They also said this was not their first call to the home this year. Narcotics agents raided the mobile home in July and found drugs. There have been reports of domestic problems as well.
"There have been some custody shifts back and forth," Chance said. "The child has stayed with different family. There has just been some things that in the mix in recent history as well as DSS has been involved with the family before."
Late Tuesday, police said the little girl's father flew into town to assist with the investigation.
Police said there are several registered sex offenders who live in the neighborhood, and were checking them out, but they cautioned there was no initial evidence that they were involved in the girl's apparent abduction.
Police still aren't saying if any relatives are suspects, they say it remains a confusing and disturbing case.
