SIGNAL MOUNTAIN, HAMILTON COUNTY (WRCB)--The human remains, believed to be that of Gail Palmgren, are en route to UT Knoxville's Body Farm for positive identification.

Hamilton County Sheriff's Office Spokeswoman Janice Atkinson tells Channel 3, members of the UT forensics team have collected the remains, suspected to be Gail Palmgren. In Knoxville, forensic scientists will try to positively identify the remains.

The missing Signal Mountain mother was last seen on April 30, leaving her Ridgerock Drive home.

Atkinson says, gathering evidence has been "slow-moving" and "painstaking" due to the size of the rugged terrain.

She says plans for removal of the Jeep Rubicon are still in the works.

Atkinson says crews spent the majority of Friday night and Saturday morning rigging rappelling lines to access the scene. At one point, a crane was used to move crews and equipment around the mountain.

Atkinson says investigators will be able to cover the scene, should weather pose a threat.

Thursday, the missing mother's ruby red Jeep Rubicon was found within the first hour of an air search.

Hamilton County Sheriff Jim Hammond tells Channel 3, the vehicle was found resting against an uprooted tree, down a steep cliff.

He says personal items were found around the wreckage, including a cell phone inside the vehicle and a purse with identification nearly 100 feet away.
