The mother of the child told KATU News she thinks the suspect came into her home and took the child.
"I believe she came into the house," said Renee Ershbock. "There were things taken from our house, taken from our porch, such as blankets, that he couldn't carry by himself."
Police said the parents of Arly Ershbock, 2, came forward to claim him Sunday after he was found with a woman who was not his parent or guardian.
Police said Arly was taken into protective custody after he was found in the arms of 30-year-old Lisa Kemper, who was wearing men's underwear and acting strangely, according to witnesses who called police.
On Monday, video footage of what appeared to be Kemper carrying the child down a North Portland street was given to KATU News by a neighbor who lived across the from the family.
The video, shot from the upper floor of Rick Eberhart's home, shows a person carrying a child in a blanket down North Failing Street near his home.
Eberhart told KATU News that he installed a video security system in his home several years ago after having some incidents of property theft at this home. 
When he heard about the incident with Arly, he checked his recordings and located footage of Kemper carrying the buy down the street in a blanket.
Renee Ershbock said she believes Kemper came into her home at some point and took Arly and the blanket.
"He could have never carried those blankets and his coat anywhere," she said. "At worst, he was on the porch, but that just seems crazy to me."
Ershbock said when she first noticed her son was missing, she assumed he was with his grandparents, who also live at the home.
"They take the kids to church on Sunday and when we woke up we just figured they were with grandma and grandpa," she said.
Local residents in North Portland who saw Kemper with the child on North Mississippi Avenue notified police when they became concerned with her behavior.
Police said Kemper has mental health issues and has a history of drug use. She was taken to a holding facility pending a Monday court appearance.
Angel Berrera told KATU News he had seen Kemper in the area on several occasions talking to herself and wandering around "like she was lost."
Kemper was not able to identify the boy and police determined he did not belong to her. Police said the boy was found with her a few blocks away from where his parents live. He did not appear to be hurt.
Police investigated how the boy became missing before they released him back into his parents' custody. They interviewed his parents and grandparents.
The parents and grandparents of the boy live at the same address in North Portland and it was initially thought there may have been a communications mix-up in the family on who was taking care of Arly Sunday morning.
