AURORA (AP) — Police searching for a 6-year-old boy say that at least one of the steps his mother took before she committed suicide – a step that suggested the boy was safe — did not happen.

Earlier this week, authorities said that after they found the body of Amy Fry-Pitzen in a Rockford hotel May 15, they discovered Timmothy Pitzen’s car seat was not in the car. That led them to believe Fry-Pitzen may have left the car seat with whomever she left her son.

But Saturday, Aurora Police Chief Gregory Thomas said in a news release that the boy’s grandmother had taken the car seat a week earlier.
