MELVERN, Kan. (AP) – A woman charged with killing an expectant mother and cutting the baby from her womb was showing the child off to people at a cafe and to her pastor hours before she was arrested, residents said Saturday.

Lisa M. Montgomery, 36, was charged with kidnapping resulting in murder and was expected to appear in federal court Monday. The baby, whose mother had been eight months pregnant, was in good condition.

Hours before her arrest, Montgomery and her husband showed off a newborn girl at a restaurant, said Kathy Sage, owner of the Whistle Stop Cafe.

Many customers were surprised to hear the infant was only a day old, Sage said. She knew an Amber Alert had been issued for a baby missing from Missouri but did not realize the infant the Montgomerys carried was connected until hearing from a reporter on Friday.

“You read about this stuff,” she said. “It blows you away when it’s here. This stuff is supposed to be in New York City or Los Angeles.”

Montgomery was arrested later in the death of Bobbie Jo Stinnett, who was found Thursday in a pool of blood inside her small white home in the northwest Missouri town of Skidmore.

Montgomery’s husband, Kevin, has not been charged in the case.

Authorities said Montgomery contacted Stinnett through an online message board, and investigators zeroed in on her using computer forensics. Montgomery was seeking to buy a dog from Stinnett, who raised rat terriers.

While the couple ate breakfast, another customer showed the baby off around the cafe. After eating, they took the girl to visit their pastor.

“It was a beautiful baby,” Mike Wheatley said. “Absolutely beautiful.”

Wheatley and his wife commented that the baby, whom the couple called Abigail, did not look like a newborn because her head was not misshapen from passing through the birth canal, a common result of childbirth that soon goes away. The only marks she had were a small scratch on her head and a slight bruise on her hand.

The pastor had not seen the couple since October, and everyone in the congregation expected her to give birth around Dec. 12.

Investigators searched Stinnett’s computer and found the victim had been communicating through an Internet message board with someone claiming to be a Darlene Fischer who lived north of Fairfax, Mo.

Authorities, helped by a North Carolina dog breeder who was familiar with the message board, determined the communication from Fischer actually came from Montgomery’s house.

The Montgomerys were taken in for questioning Friday, and Lisa Montgomery was charged. Investigators said she confessed to the crimes.

Officials said Montgomery had not hired an attorney. Messages left by The Associated Press at the home of Kevin Montgomery’s parents went unreturned Saturday.

Jeff Lanza, an FBI spokesman in Kansas City, Mo., declined to discuss motives and said the investigation was ongoing.

He would say only that Montgomery was being held in Kansas and was expected to make her first appearance in federal court Monday, though authorities did not know whether it would be in Missouri or Kansas.

The baby girl, named Victoria Jo, was in good condition Saturday. Several family members, including her father, had been reunited with her at a hospital late Friday.

The infant was in an intensive care unit. Hospital officials said she was responding normally for a baby taken from the womb one month premature.

“She’s doing well,” said Carol Wheeler, a spokeswoman for Stormont-Vail Regional Health Center.

The family was not speaking to reporters, but the child’s father, Zeb Stinnett, issued a brief statement calling the child “a miracle.”

“I want to thank family, friends, Amber Alert and law enforcement officials for their support during this time,” he said.

U.S. Attorney Todd Graves said Montgomery contacted Stinnett through an online message board after seeing a Web site about rat terriers that Stinnett bred and raised. The site included a picture of Stinnett, showing she was pregnant.

Montgomery is the mother of two high-school-age children, but Graves said she had been pregnant with another child that was never born. It was unclear when she lost the baby or under what circumstances, but the complaint said she had lied to her husband about giving birth.

Nodaway County Sheriff Ben Espey said Saturday that Montgomery had told people she was pregnant with twins, though investigators were still trying to determine if that was true.

“She told people she was pregnant and had a miscarriage and lost one of the twins,” Espey said. “We’re thinking she never was pregnant.”

According to court documents, Montgomery traveled to Topeka on Thursday to go shopping. She called her husband from there, saying she had gone into labor and given birth.

Kevin Montgomery and the couple’s two children met Lisa and the newborn in the parking lot of a fast-food restaurant in Topeka and drove home, according to an affidavit.

The arrest stunned many townspeople who apparently had believed for months that Lisa Montgomery was pregnant.

How “could you not know that your wife’s not pregnant?” said Gary Deskins, owner of a convenience store in Melvern, a community of about 420 residents about 30 miles south of Topeka. “There’s something missing.”
