The search for a missing 6-year-old Aurora boy has been called off, nearly a week after he was last seen with his mother who was later found dead of an apparent suicide.
Authorities said the search would resume if new, specific information came in as to the whereabouts of Timothy Pitzen.
"It's frustrating. Every day that goes by reduces the chances for a good outcome," said Aurora police Lt. Pete Inda.
More than 70 people from various agencies, including the FBI, the U.S. Marshals Service, the Illinois Department of Corrections and police from Aurora, Dixon and Sterling, used dogs and planes Thursday to search for the boy, focusing their hunt in their area of Dixon, Ill.
Pitzen and his mother, Amy Fry-Pitzen, were last seen last Friday, checking out of the Kalahari Resort in Wisconsin Dells, Wis.
A day later, Amy Fry-Pitzen was later found dead in a Rockford motel room. Authorities said she'd slit her wrists. She left a note indicating her son was safe and left in someone's care but didn't specify any names.
Despite pleas from the boy's remaining family, whoever has Timothy Pitzen hasn't come forward.
The search for Timothy Pitzen went to the Sterling/Rock Falls area on Wednesday because that is where the mother's cell phone was last used.
Timothy stands about 4 feet, 2 inches tall and weighs about 70 pounds, officials said.
Anyone with information is asked to call Aurora Police at 630-256-5500.
