John Robinson connected with Lisa Stasi, and then put her and her daughter up in the Rodeway Inn hotel in Overland Park, Kansas, according to police.
On Jan. 8, 1985, Stasi drove her baby over to the home of her sister-in-law, Kathy Klinginsmith, to help with babysitting and told Klinginsmith about Robinson.
Klinginsmith told "20/20" she "felt uneasy" about their conversation and that the next day, in the middle of a snowstorm, John Robinson showed up at her home and took Lisa Stasi and the baby back to the Rodeway Inn. That was the last time Lisa Stasi was seen alive.
Hours later, Lisa Stasi's mother-in-law Betty Stasi said that she received a strange call from her.
"She just called and she was hysterical. She was crying hard," Betty Stasi said.
"I said, 'Don't sign nothing.' And she was just crying and then she finally settled down and she says, 'Here they come now'...And she hung up. And that was the last time I heard from her," Betty Stasi said.
"She disappeared forever," Klinginsmith said.
"Here THEY come now."
