AURORA, Ill. (CBS) — Blood belonging to a 6-year-old missing Aurora boy whose mother committed suicide has been discovered in the woman’s van, although police say it could have been the result of a mere bloody nose.
Timmothy Pitzen has not been seen since early May, when his mother, Amy Fry-Pitzen, took off with him. The case of his disappearance has since gone cold.
Fry-Pitzen pulled her son out of school on May 11 and took him to the Brookfield Zoo. Over the next two days, they also visited the Key Lime Cove Resort in Gurnee, and the Kalahari Resort at Wisconsin Dells.

As CBS 2’s Mike Puccinelli reports, Fry-Pitzen left a note saying Timmothy was in someone’s care, but she didn’t say who. It also said he was with people who love and care for him and had a statement that he will never be found.
Police seized Pitzen’s 2004 Ford Expedition sport-utility from the parking lot of the motel after her body was found. When the SUV was found, it was visibly dirty, and weeds were found under it, Aurora police said.
Aurora police turned the van over to a private lab, in hopes that substances on the van would prove unique to some areas in western Illinois where Timmothy and his mother were last known to be together. Detectives know they were together in the Interstate 88 and 39 corridors in the Dixon-Rock Falls-Sterling area.
The lab did end up finding blood staining the back seat that turned out to belong to Timmothy. But it is not known how long the blood was in the vehicle, and family members tell police it could have been from a bloody nose he suffered in the past year or year and a half.
Only Fry-Pitzen’s own blood was found on the knife she used to commit suicide, police said.
Fry-Pitzen has no connection to the area where she committed suicide, nor to the region where she was last seen with her son. But it turns out that she took two trips to the Dixon-Rock Falls-Sterling area before her death that family members cannot explain, police said.
Her I-Pass records show she traveled to the area on the afternoon and evening of Feb. 18, and the morning and afternoon on March 20.
Fry-Pitzen’s cell phone and I-Pass have not been found, nor have Timmothy’s Spider-Man backpack and toys.
Police say the clothes Fry-Pitzen was wearing when she was seen on surveillance videos are also unaccounted for. They include a pair of brown Capri pants, a white or light pink shirt, and a pair of high-soled, sandal-type shoes, police say.
Police previously released pictures of toys similar to the ones Timmothy had with before he disappeared. They include an “Aquatic Rig” toy truck made by Wild Republic toys; Kalahari Resort commemorative coins with pictures of giraffes, lions, elephants and other wild animals; an Iris brand plastic craft case, a Hot Wheels toy race car starter set, and a tube of kids’ Crest toothpaste.
Anyone in the area is asked to be on the lookout for items.
Police have also released surveillance video of Fry-Pitzen taking Timmothy out of school on May 11.
Also out is a two-part home video of Timmothy from November of last year. In the home video, he is seen in pajamas pretending to play a guitar made from with Tinkertoys.
Timmothy is about 4 feet 2 inches tall and weighs aro
und 70 pounds, with brown hair and brown eyes.
Anyone with information on the case is asked to call Aurora Police at (630) 256-5500, or their local authorities by dialing 911.
