The Portland Police Bureau said in a written statement that the mother of the three kids had been located but did not provide her identity or any details on why she allegedly ditched her children the night before.
The children were discovered Friday morning by officers investigating a report from a resident on the southeast side who had seen transients in the yard of a vacant home in the southeast side neighborhood. The officers found a group of transients taking shelter from the rain inside a shed in the back yard, along with the male and female toddlers and an infant girl.
Police said the ages of the children were about 3, 2 and 1 and their identities were unknown.
"The homeless persons told the officers the children had been abandoned there the night before by a woman whom they believed was the children's mother," police said. "The children were immediately taken into the protective custody of DHS and were medically evaluated to check their welfare."
Neighbor Judy Baxter told The (Portland) Oregonian she saw one police officer carrying the baby while the two older children left the shed holding the hands of officers. She said the older youngsters were bundled up in coats and carried backpacks.
"Little did I know they had three babies in the backyard," Baxter said. "It was real sad when we saw the kids come out."
