DENVER -- A U.S. Forest Service employee accused of starting the largest wildfire in Colorado history bonded out of jail Thursday afternoon.

Terry Barton will have to stay at a halfway house until her trial on Aug. 26.

As a part of her release, the 38-year-old Forest Service technician is required to get mental health counseling and is not allowed to leave the state or enter a forest.

Barton's two teen daughters are staying with her sister in California since the family has received several death threats.

Barton's estranged husband, John, on Wednesday agreed to use their home as security for her $600,000 bail.

Terry Barton faces four federal charges including arson for allegedly starting a 137,000-acre blaze in the Pike National Forest that destroyed at least 115 homes and cost more than $27 million to fight.

The Hayman Fire, which has been burning since June 8, is currently 85 percent contained. Full containment is expected by 6 p.m. Friday. Most of the 8,200 people who had been evacuated during the course of the fire are now home.

About 880 people are still out of their homes, according to the Rocky Mountain Coordination Center.

U.S. District Court Judge Richard Matsch sealed the address of the property to be used as bond, the address of the halfway house where Barton is staying, and John Barton's current address.

Information relating to Terry Barton's required mental health counseling was also sealed.

Barton, an 18-year Forest Service employee, was indicted by a federal grand jury and was being held in a Jefferson County jail in Golden.

Teller County prosecutors may also file state charges against Terry Barton because a 50-year-old woman's death has been linked to the fire.

Ann Dow died after smoke engulfed her home near Florissant three days after the fire started . Her doctor listed smoke inhalation and asthma as the cause of death.

Investigators from the Teller County district attorney's office planned to meet with Gary Dow, her husband, on Thursday.

Dow said he does not plan to file a lawsuit.

"When the dust settles, I may feel differently, but I don't think there was any intent," Dow said. "But at the same time, I lost my wife."

No autopsy was performed, a fact that could complicate a prosecution, county prosecutor Dan May said.

If convicted on the federal charges, Barton faces up to 60 years in prison and $1 million in fines.

Federal prosecutors allege that Barton deliberately set the fire and staged the scene to make it look like a runaway campfire.

She allegedly confessed to accidentally starting the fire while burning a letter from her estranged husband.

John Barton told investigators that he never wrote her any letter.

Friends said Barton had been struggling with a failing marriage and is trying to obtain a divorce before the accusations.
