UPDATE: The family of a woman killed in a plane crash last year has filed a wrongful death lawsuit against the pilot's estate on January 7.

Lynda Marinello and the pilot, Frank Davey, were both killed when Davey's plane crashed into Chickamauga Lake last January.

The lawsuit claims Davey was negligent and reckless for performing "acrobatic maneuvers" at an "unusually low altitude".

The Marinello family is asking for at least $500,000 in damages.

PREVIOUS STORY: The Hamilton County Sheriff's Office says a portion of the plane that crashed on Chickamauga Lake this week has been removed from the water.

HCSO spokesperson Matt Lea says the fuselage, or the main portion of the plane's body, has been removed.

Lea says the wreckage will be taken to a secure location for the NTSB's investigation of the crash.

The plane crashed on Monday and was finally found 35 feet below the water surface on Thursday afternoon.

The two people in the plane at the time of the crash, Frank Davey and Lynda Marinello, were also found with the wreckage.

Both victims were long-time educators at Notre Dame High School in addition to Davey being a pilot.

PREVIOUS STORY: The plane that crashed into Chickamauga Lake on Monday was found Thursday along with the people who were in it following a 4-day search.

Family members said the wreckage was found around 3:00 pm.

The Hamilton County Sheriff's Office says the plane is 35 feet below water.

"The HCSO will oversee the recovery of the airplane, but the actual efforts to salvage and lift the airplane from the lake bottom will be conducted by private contractors in partnership with the victims insurance company responsible for insuring the aircraft," Matt Lea with the HCSO said.

Lea did not release the names of the bodies that were found in the plane.

He says, "Investigators will work with the Medical Examiner’s Office to confirm the identity of the two victims."

The sheriff's office said they will continue to gather evidence that will be turned over to the National Transportation Safety Board (NTSB). They will determine the cause of the crash.

PREVIOUS STORY: Rescue crews spent several days trying to locate a plane that crashed Monday into Chickamauga Lake.

A half a dozen crews were back out on Chickamauga Lake looking for the aircraft that crashed into the water, with efforts since changed from rescue to recovery.

Divers have identified several areas of interest underwater, which will be investigated Thursday.

Hamilton County Sheriff's Office spokesman Matt Lea explained that while surface waters appear calm, underwater currents are hampering recovery efforts and complicating the investigative work.

Thursday's colder temperatures made the divers' and recovery crews' work even more challenging.

Lea also explained that the partial federal government shutdown has affected the investigation, but in relatively small ways. They are keeping NTSB officials updated on their investigation.

Recovery crews have nearly a half-dozen boats on the lake, each with several crew members aboard.

“We have got a systematic approach that we use,” said Mark King. “We've been trained in this, and unfortunately we weren't recoveries before on the river.”

Mark King, the Deputy Chief of Law Enforcement, says boat crews were out early on the water, searching for any evidence.

“With some of our systems we have sight scans, sonars, and things of that nature that they are using it right now to search that generalized area,” said King.

King says these boats are searching near the 3000 Block of Lee Pike in northern Hamilton County.

He says they have dive teams on standby.

“Putting divers in the water is the unknown, and it's a little bit more dangerous. So we're going to try to locate first,” said King.

King says once they have located the aircraft underwater, divers will go scope out the scene.

That will determine what steps will be next.

“There, depending on what they find and how they find it will be how they determine recovery efforts, at that point,” said King.

Authorities concluded their search around 6 p.m. on Tuesday.

They will continue their search first thing Wednesday morning.
