Another school district employee notified authorities of computer porn
A now-former high school teacher in Dallas pleads guilty to three counts of receiving child pornography and
one count of possession of child porn.
U.S. Attorney James T. Jacks says Jon Leslie Lyons entered his plea before a federal magistrate Wednesday.
The 44-year-old Lyons has been in custody since his June arrest.
An affidavit says a Dallas school district employee in May notified federal authorities after discovering possible child pornography on a school computer assigned to Lyons.
Lyons, in a later interview with agents, admitted he also had images of nude teens on his home computer and cell phone.
Lyons faces a maximum 70 years in prison and a fine of up to $1 million.
