DALLAS (KRLD) – Yesterday, Dallas hospitals were put on alert about Misty Lynn Wallace and Walter Ray Stall, a suspicious couple posing as adoptive parents and asking about a baby.

Wallace claims she was tricked.

“I started to think ‘This man’s full of it, there’s no baby’,” she says.

Wallace met Stall on the dating site Mingle2. They communicated for only two weeks before Wallace says Stall promised to buy her a house and a car.

“Then he says ‘We need to talk’. And he tells me his friend is having a baby she can’t take care of,” says Wallace. “And he asked me to take care of the baby with him.”

Wallace says from the start, there was conflicting information about which hospital the baby would be born in. But she says Stall promised he would make the arrangements.

“Then I went through his phone,” she says. “And all the times he said he called the hospital, he never actually spoke to anyone. He just dialed the number and hung up. I started to think this baby doesn’t exist.”

Wallace says eventually Stall told her the baby was at Parkland Hospital. While Stall went inside the hospital to ask Parkland nurses about the baby, she claims she waited outside.

“Supposedly the nurses wouldn’t let us see the baby without adoption papers,” she says. “And apparently he asked them how he could get a baby.”

No baby was taken from Parkland or any hospital. The alert was issued after Wallace and Stall left Parkland. Police spoke to both of them, and Wallace claims she told police her suspicions.

After a confrontation with Wallace, Stall disappeared. He hasn’t been seen since. He still tries to contact Wallace, and she’s keeping police informed when he calls. Wallace says police have told her she won’t be arrested if she continues to work with them.

What she can’t say for sure is why he would try to trick her this way.

“I think he was trying to please me, because he’s lonely and sick and getting on in age,” Wallace says. “I guess he figured if he could sweet talk me into believing him, I’d wind up taking care of him.”

But Wallace says she has no plans of adopting her own baby.

“If all this were true I would have taken care of this baby because his friend couldn’t,” she says. “But I’ve had enough dealings with kids. I have 11 stepchildren. I’m not at an age to raise a baby anymore.”
