Lisa Irwin is 10 months old and was last seen in her crib when her mother had checked on her. She was reported missing 5 hours later when her father came home after a late night shift at work.

Around 300 officers  are trying their best, looking out for the baby using helicopters, searching all terrain vehicles and conducting door-to-door interviews to find  the little girl from Missouri who went missing late Monday night.

Her parents tearfully begged to whoever has taken the baby to leave her somewhere safe. Please drop her off anywhere, her father, Jeremy Irwin, calmly said during a brief news conference at a makeshift police command center near their home. We don't care. Somewhere safe so she can come home.

We're going to keep working as long as calls come in and we think there's absolutely anything we can do, Capt Steve Young, an official,  said late Wednesday.

He also said that the child's parents are not suspected and they have been cooperating from the start of the investigation, adding that so far, the investigation has got no leads to follow and has no suspects.

According to police officials, the one possibility that they are working on is that someone entered from the front door and took the baby away, since there were no signs of forced entry into the house.

The missing baby girl has blue eyes, blonde hair, is 30 inches tall and weighs around 28 pounds. The clothes in which she was seen last were purple shorts and a purple shirt with pictures of white kittens on it.

FBI agents have already used search dogs in the family's home, but the details of the investigation were denied by the FBI spokeswoman.

Everything we've thought of doing we've probably done two or three times, Young said. Over 300 law enforcement officers have been involved. They've walked a wooded area three times in shoulder-to-shoulder searches, taken dogs in three times - different dogs each time - and none of those led us anywhere.
According to a neighbor's account, the kid's parents seemed to be wonderful caretakers.

Ernie Allen president of The National Center for Missing and Exploited Children said that of the 278 infant abductions nationwide over the past 28 years, only 12 of those children didn't come home safely, the report said.

Police had issued an Amber Alert on Tuesday morning but called it off after 12 hours. Police said it was a formality because the alerts are designed to raise awareness early in an investigation.
