Kristen Smith is the aunt of the newborn, Kayden Powell, who was kidnapped from the home and later found outside an Iowa gas station.
Police believe Smith took the child, then dumped him when family members and police became suspicious. She's charged with kidnapping.
Family members want her to pay for what she did.
"She should be totally punished to the max. She had plenty of time when they arrested her, to tell them that boy was out by that gas station," said Shirley Bennett, Kayden's great grandmother.
Smith is also wanted in Texas on fraud charges. It's unclear when she will be extradicted from Iowa or whether she'll be sent first to Texas or Wisconsin.
