Defense attorneys have told a federal judge in Spokane that a last-minute plea deal is unlikely in the case of a U.S. Forest Service crew boss charged in the 2001 deaths of four Washington firefighters.

Ellreese Daniels, 47, will likely stand trial May 5 on four counts of involuntary manslaughter for allegedly making decisions that led to the deaths of the firefighters as they were trapped by the Thirtymile Fire near Wenatchee.

During a pre-trial hearing, Daniels’ public defender said that her client will not accept prosecutors’ offer of pleading guilty to a felony to avoid going to trial.

The trial is expected to last at least a month.
