Forensic technicians working to find a missing Aurora boy, plan to retest tall grass and weeds recovered from the bottom an SUV belonging to the boys mother.
Amy Fry-Pitzen was found dead of an apparent suicide in a Rockford motel room on May 14, and her son, Timmothy, has been missing ever since. She was last seen alive, with her son, a day prior at a resort in Wisconsin Dells, Wisc. A note left behind in the motel room said the 6-year-old boy was safe and in someone's care, but did not indicate whom.
Geologists and other specialists hope the plant growth found underneath the 2004 Ford Expedition will be unique to certain areas in the Rock Falls/Sterling/Dixon area, where Fry-Pitzen and her son, were last known to be together.
Despite a massive search that's ensnared federal authorities and taken investigators from Aurora to Dixon to Rock Falls, the boy is nowhere to be found.
"I miss my son and my wife a lot," said the boy's father, James Pitzen. "[There's a] big hole in my heart, just waiting for him to come home."
Authorities on Wednesday also released photos depicting several items Fry-Pitzen is believed to have purchased for her son in the days prior to her death. The items -- a craft kit, toy cars and a tractor-trailer, gold coins and toothpaste -- have not been located. If they're founacd, it could help locate Timmothy, police said.
Other avenues police are investigating, including computers, personal records, and interviews with "dozens" of people, have turned up no solid leads, they said.
Timmothy stands about 4 feet, 2 inches tall and weighs about 70 pounds, officials said.
