The Tennessee Bureau of Investigation is reviewing the case of a missing Signal Mountain woman at the request of the Hamilton County District Attorney's Office.
Gail Palmgren, 44, of Signal Mountain, has not been seen since April 30. Her sister, Diane Nichols of New York, contacted the district attorney's office, asking for a review.
"We have been asked to take a look at the case and see if we have any suggestions," said TBI Special Agent in Charge Jerri Powell in Nashville.
The Hamilton County Sheriff's Office still is leading the investigation into Palmgren's disappearance.
Matthew Palmgren, Gail's husband, told police that the last time his wife was seen by family members, she left their children, ages 9 and 12, alone at their home at 40 Ridgerock Drive. Her crimson-red Rubicon Jeep also is missing.
Two days later, at the urging of Nichols and other family members, Matthew Palmgren filed a missing persons report with the Signal Mountain Police Department. The report came only days after police responded to arguments between the Palmgrens at their home on April 22 and April 29, according to reports.
Investigators have found no evidence of foul play. Matthew Palmgren recently reached an agreement with authorities and allowed them to search the couple's Signal Mountain home two months after his wife was last seen.
Other searches are being coordinated for other family properties.
Matthew Palmgren lost his job at BlueCross BlueShield of Tennessee after authorities began searching for his wife. According to tax documents, Matt Palmgren earned more than $230,000 in 2009.
Nichols and another sibling, Kevin Nowacki, recently filed a restraining order in Hamilton County Chancery Court to appoint a legal representative for the children and to ask that Matthew Palmgren not be allowed to move the children more than 100 miles from their home.
The filing also asked the court to protect their sister's assets.
A judge dissolved the order last week.
