DENVER -- A Colorado woman has been charged with kidnapping in the case of a Wisconsin newborn who was taken from his home early Thursday.
Kristin Smith is the half-sister of the baby's mother, Brianna Marshall.
According to Smith's arrest affidavit, Smith had come to visit the family in Beloit, Wisc. She left the home Thursday morning. Several hours later, Marshall told authorities that her baby was missing.
The child, Kayden Powell, was found in a tote bag at an Iowa gas station Friday, police said. The baby was healthy and responsive, police said.
Smith was arrested at a West Branch, Iowa gas station on a unrelated warrant out of Texas. According to the affidavit, she had baby clothes in her car, a fake pregnancy belly and a stroller.
Kayden was found about 500 yards away from where Smith was arrested.
The baby's great-grandfather, Brian Bennett, told the Associated Press that he was "surprised" the child was in good condition.
"It's funny he lived that long outside. A miracle, I guess," Bennett, 68, said. "They were just lucky they found him."
Authorities were working Friday on reuniting the baby with his family.
