UPDATE (WKOW) -- Aurora Police have confirmed that Timmothy Pitzen's child car seat that was thought to have been missing from the vehicle driven by his mother, has been in the possession of Amy Fry-Pitzen's mother since before the two went missing.
The grandmother took possession of the seat when she cared for Timmothy a week prior to Amy Fry-Pitzen taking off with Timmothy. When the grandmother returned Timmothy home, she forgot the child seat.
The boy's Spider Man backpack along with toys and clothes purchased by his mother while they were in Wisconsin are still not accounted for.
Timmothy has been missing since May 13.
AURORA, Ill. (WKOW) -- Authorities continue their search for a 6-year-old boy who was last seen with his mother at a Wisconsin Dells resort last week.
The missing boy, Timmothy J. Pitzen, is described as 4'2", weighs approximately 70 pounds, and has brown hair and eyes.
The Aurora Police Department says his mother, Amy Fry-Pitzen, 43, killed herself on Saturday inside of a Rockford motel room and left a note saying the boy was fine and was in the care of unnamed persons.
Police say Timmothy's child safety seat and backpack are missing from the vehicle Fry-Pitzen was driving, which detectives say could support the theory that Fry-Pitzen may have dropped off Timmothy with a friend.
Police say Fry-Pitzen checked Timmothy out of his Aurora elementary school last Wednesday without telling her family or friends. She then spent the afternoon with him at the Brookfield Zoo and eventually checked into the Key Lime Cove Resort in Gurnee, Illinois on Wednesday night. From there, the pair traveled to the Wisconsin Dells and were at the Kalahari Resort until around 10:00 a.m. Friday. They were last seen together checking out of the resort.
Between approximately 12:00 and 1:30 p.m. on Friday, police say based on cell phone records, Fry-Pitzen and Timmothy were in the Sterling/Rock Falls, Illinois area where Amy placed several calls to family and friends; the first contact she had with anyone since checking Timmothy out of school. It was during those conversations that Amy said she and Timmothy were fine and were not in any danger.
Police say Fry-Pitzen was seen without Timmothy at Sullivan's Foods in the 700 block of Elida Street in Winnebago, Illinois at around 8 p.m. Friday; and when she checked herself into the Rockford Inn, located in the 3800 block of 11th Street, between 11:15 and 11:30 p.m. Friday.
Fry-Pitzen killed herself sometime between the time she checked in on Friday and when her body was found at around 12:30 p.m. Saturday. Timmothy has not been seen or heard from since talking on the telephone with relatives on Friday.
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 their local authorities by dialing 911.
