Sadly the search for little Timothy has been called off until LE receives further specific information pointing them to Timothy's whereabouts.
Search for Missing Aurora Boy Called Off
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.

Because the family will now be doing much of the search for Timothy on their own I am going to add a number of resources which can assist the family in this area.
LostnMissing Inc.
When a loved one becomes missing, families are extremely distraught. Working along with their law enforcement we will guide families to what needs done to help locate their missing family member. This includes media, marketing, designing missing posters and banners, and assisting the family with needed events as well as contracting for search and rescue, if advised by their local police agency. We are always available to the family and work with professionalism and compassion.

Project Jason.

Of the two above from my experience LostnMissing is more hands on working directly with family and guiding them through the process. I don't have as much knowledge of how Project Jason works other than they are another excellent resource.

An additional forum specifically dedicated to resources for the family of missing persons can be found here:
Families of the Missing-Resources, helps, tips - Websleuths Crime Sleuthing Community
Organizations that can help - Websleuths Crime Sleuthing Community
I will add to the above list as I find more resources. The above should be a fantastic start for the Fry-Pitzen family.
