BOULDER, Colo. -- One of the four teens held in the stabbing death of 52-year-old Linda Damm, of Lafayette, was released Thursday on a reduced bond.

The Longmont Times-Call and Boulder Daily Camera said bond was reduced for 18-year-old Jared Guy after he agreed to cooperate with prosecutors.

Guy is accused of helping the others try to dispose of Damm's body. His bond was lowered from $50,000 to $5,000 and he was released. He has tentively agreed to testify against his friends, the newspapers said.

Bryan Grove, 17, is charged with first-degree murder in the case. Damm's 15-year-old daughter, Tess, is charged as an adult with conspiring to kill her mother and other charges.

Charges are still pending against another teen, Jared Smith. He was arrested on suspicion of conspiracy, accessory and tampering with evidence.

Damm's body was discovered in late February, nearly a month after she was stabbed to death.

In his arrest affidavit, Guy said that he helped his best friend and "brother" try to bury Damm's body. They tried to first dump her in an Erie landfill but their car got stuck in the mud so they turned around, he said. They then tried to bury her in a cemetery near Guy's high school, but they had not dug the shallow grave deep enough and there was a visible hump where she was buried, the affidavit said.

The teens worried that the body would be discovered so they dug the body back up and stuffed it in the trunk of her station wagon, which they parked in the garage, where it was found by police officers weeks later, police said.

Guy was arrested the night of his winter dance at Standley Lake High School, when he had planned to propose to his girlfriend.

He told detectives that he was just trying to help Grove and had tried to convince Grove to go to the police. The two are very close and call each other "brother." Both were adopted by Boulder County families from an orphanage in India, the Daily Camera reported.

Guy was recently awarded the Metropolitan Mayors and Commissioners Youth Award by the Boulder County commissioners for overcoming adversity and for serving as a role model to other students.

Guy was ordered not to have contact with Damm or Grove and Damm's family.
