Ochsenbine was released from St. John's Mercy Medical Center in suburban St. Louis on Sunday. In an interview on the CBS Early Show, her mother, Raylene Ochsenbine, said "emotionally, she's starting to crumble a little bit more even, if that's possible."
Investigators are hoping a break in the case will come from the public. Police are distributing both a photo of the baby, born Sept. 8th with a strawberry birthmark on her forehead, and a sketch of a woman they suspect kidnapped the child after slashing Ochsenbine in the family's home in Lonedell, Missouri - about 45 miles southwest of St. Louis.
Police say Ochsenbine's 1-year-old son, Connor, was also in the house at the time but was not harmed. Ochsenbine's boyfriend and Abby's father, James Woods, was at work.
The police sketch of the suspected kidnapper shows a woman with dark hair wearing a baseball cap. Franklin County Sheriff Gary Toelke said the suspect is believed to be between 5 feet 4 and 5 feet 8 and weighs about 200 pounds.
Toelke said Ochsenbine "wasn't completely happy" with the sketch, "but it's the best we could come up with." He said more than 300 leads have come in so far.
"The phones have been ringing off the walls," he said at a news conference. "We did find the knife outside the residence that we feel may be significant. We did find other items in the residence and outside the residence."
Authorities are awaiting lab results on fingerprints found on the knife.
"We are still getting leads and still moving forward and still asking people to call in if they have any suspicions, give us a call so we can check it out," Toelke told The Early Show co-anchor Julie Chen.
"Any lead is good, but so far there's nothing that has stood out," he said. "There's a lot of information we have, but nothing concrete."
"We have a lot of law enforcement involved, the FBI is helping us, our local highway patrol, people from the missing and exploited children's network, and behavioral scientists from Quantico (FBI Academy)," Toelke added.
Search dogs, Franklin County deputies, FBI agents and 100 Missouri National Guard members did a grid search over the weekend of the area around the home.
Authorities are hopeful that the baby is alive and well.
"From history, if somebody wants a child, I would assume that child's being taken care of," said FBI agent Roland Corvington said.
The abductor has been profiled as someone who had a child die recently or as someone who could not have children, told people she was pregnant and decided to steal a child so that her lie would not be found out.
"Historically, these types of people have cased hospitals," said Corvington.
The attacker is believed to be armed, and may be posing at the baby's mother. The sheriff describes the woman as heavyset with dark hair, some slight facial hair, "a pretty large-sized female."
Authorities have asked hospitals and doctors to be on the lookout for anyone bringing in a newborn.
Fliers showing the baby, called "Abby" by her family, have been posted in gas stations and restaurants in neighboring Union. The 6-pound girl, born Sept. 8, has dark brown hair, dark eyes and a strawberry birthmark on her forehead.
People in the area, about 45 miles southwest of St. Louis, attended church services Sunday to pray for Abby's safe return.
Ochsenbine told police she did not know the woman who came to her door Friday and entered the house after asking to use the telephone.
From 1983 to 2002, there were 217 reported cases of non-family infant abductions, and all but a few babies were recovered safely within 25 miles of where they had been taken, according to a 2003 study by the National Center for Missing and Exploited Children. About three-quarters of the kidnapped infants were recovered in fewer than five days.
