As of 2:45 p.m. Sunday, the boy remained missing and there have been no arrests, according to according to Aurora spokesman Dan Ferrelli.

Meanwhile, police are continuing to seek leads and information from multiple jurisdictions.

“We’re working with authorities in Iowa and Wisconsin and we are continuing to cultivate other individuals that she’s (his mother) associated with and we’re trying to talk to those individuals,’’ Ferrelli said.

Numerous family members and friends of his mother, Amy J. Fry-Pitzen — including her husband — are fully cooperating with the investigation, Ferrelli said.

“So far right now, all the people we’ve talked to have been consistent…She (mother) indicated that she needed some time away and she did not threaten to harm herself or the boy.’’

Timmothy was last seen at about 10:10 a.m. on Friday when he accompanied his mother checking out of the Kalahari Resort in the Wisconsin Dells.

Amy and Timmothy were originally reported missing about 1 p.m. Thursday by Amy’s husband, who is also the boy’s father, from their home in the 400 block of North Highland Avenue, according to Ferrelli.

The two apparently visited the Brookfield Zoo on Wednesday and then checked into the Key Lime Cove Resort in Gurnee on Wednesday night.

No one heard from Amy or Timmothy until Friday afternoon when she contacted several family members and acquaintances by phone between approximately noon and 1:30 p.m., according to Ferrelli.

During those calls Amy said that she and Timmothy were fine and were not in danger. Timmothy also talked to at least one of the relatives and did not seem to be in any distress.
Aurora Police say that cell phone records indicate that the calls and texts were placed from the Sterling/Rock Falls, Illinois area.

Detectives were able to ascertain that Amy checked herself into the Rockford Inn which is located in the 3800 block of 11th Street in Rockford, between 11:15 p.m. and 11:30 on Friday night.

At the time she checked in, she apparently was not accompanied by Timmothy.

She had also been seen at Sullivan’s Foods in the 700 block of Elida Street in Winnebago, Ill., at about 8 p.m. Friday, again, apparently without her son, Ferrelli said.

The food store is about 20 minutes from the Rockford Inn.

Her body was discovered by motel employees at about 12:30 p.m. Saturday. She left a note indicating that Timmothy was fine and that she left him in the care of unnamed people.

Anyone who believes they saw either the boy, his mother, and/or anyone who may have been with them — or anyone who may have information on the case— is asked to call Aurora Police at (630) 256-5500, or 911.
