Illinois State Fire Marshals office have still not released an official cause of a deadly Lawrenceville house fire. A mother and her two children died when this house caught fire Sunday afternoon. Mary Beck, her son Trevor and her son Tyler were apparently napping at the time of the blaze. Fire investigators say the flames appear to have started near the kitchen. Autopsies were scheduled on all three victims yesterday, but no results have been released. A trust fund has been set up to help the family pay for funerals. Donations can be made at the Old National Bank in Lawrenceville. They should be sent to the attention of Leah Stultz. Funeral services will be held Thursday at 11 am at the Emmons-Macey and Steffey funeral home.
