Aurora Police uncovered new details in the case of Timmothy Pitzen, the 6-year-old boy who disappeared after his mother killed herself in May.
Officers say they retrieved 34 emails from a secret account set up by the boy's mother, Amy Fry-Pitzen.
A search warrant recently made public shows Fry-Pitzen had one Yahoo account her husband could access and one that she didn't tell him about, according to the Chicago Tribune.
FBI profilers thought the woman may have used the email to help plan her actions leading up to her suicide and disappearance of her son, but the lead investigator in the case, Detective Trent Bryne, told the paper the account "had absolutely nothing to do with Timmy's disappearance" and "a lot of it was just spam."
Detectives were not able to get records of Amy Fry-Pitzen's deleted emails because Yahoo does not maintain those records.
Timmothy Pitzen disappeared May 11 after his mother took him out of school. They stayed overnight at a water park resort in Gurnee before going to Wisconsin Dells for a night. Fry-Pitzen's body was found May 14 in a Rockford motel after police say she committed suicide.
