AURORA, Colo. -- A 6-year-old Aurora girl was still missing Tuesday, and police are worried because this may be her second day out in the bitter cold weather alone.

Arrone Thompson went missing Monday at about 1 p.m. and hasn't been seen since. Police say she got into an argument with her mother about a cookie and walked out the door, wearing little more than a white sweater, a gray hooded sweatshirt and pink sweatpants.

She is 4 feet tall, weighs 60 pounds and is missing her top right canine tooth. She was last seen wearing a ponytail with a pink rubber band and white sneakers.

Her house is located in the 16000 block of East Kepner in Aurora.

On Tuesday, more than 70 Aurora police officers canvassed the neighborhood, sifting through large garbage bins, crawling over fences, searching back yards that are easily accessible and scouring creek beds.

Police say time is the of the essence.

"Six year old girl spending the night in this kind of weather? It's not good," one Aurora officer said.

Temperatures in Aurora dipped to 18 degrees on Monday night and is expected to be 14 degrees Tuesday night.

Just before 6 p.m., the girl's father spoke to 7NEWS, pleading for the public's help.

"And I'm scared for her safety. I really don't have much to go on but what the police have ... I just want to come out here and say thank you for everybody who is looking for her and if anybody has information, please contact the police to bring my baby girl home," said Aaron Thompson, Aarone's father.

Aaron Thompsaid he hasn't been able to eat or sleep since Aarone's disappearance.

Police on Tuesday used Jefferson County bloodhounds to see if they could track her scent. The dogs went for a few miles and then stopped in an an empty field near Chambers and Alameda Avenue. Officers searched the open lot and nearby garbage bins but turned up nothing.

On Monday night, Aurora police searched the area where she disappeared and even sent out a reverse 911 call to alert residents to look for her. They also used K-9 to conduct an all-night search on Monday.

On Tuesday, Aurora police started their search all over again, going door-to-door talking to neighbors. Neighbors in that area, which is near South Buckley Road and East Mississippi Avenue, are being very cooperative.

"My sister went missing for a while, but it was a different situation. I remember that fear and it was horrible. So, it hits home when it's right in your neighborhood too, especially, and when you kind of know of the family," said neighbor Janell Black.

However, police had said that the girl's family was not being very cooperative.

"One of the issues we're facing is that the family is not as cooperative as we would have hoped they would be. And that's something we hope will change because time is precious right now," said police spokesman Marcus Dudley

This case is not considered an Amber Alert because right now, there is no evidence of foul play, police said.

Police say they will continue searching for the girl until they find some clue or until they have done the best they could to locate her.
