The Jefferson County Coroner's Office has confirmed the identities of the husband and wife killed in a plane crash near Trussville on Friday night.
The victims have been officially identified as Joseph Allan Campbell, 44, and Calli Miller Campbell, 46. They had four children.
NTSB officials said Monday that the plane was carrying two vials of blood to Birmingham, but they are not sure why. They are hoping to find out tonight what the blood was for and who was receiving it.
The NTSB is in the process of removing the wreckage of a small plane that crashed into a mountain between Lake and the Woods and the Goodner Mountain of Jefferson County on Friday night.
Crews from Atlanta Air Recovery arrived Tuesday morning with their equipment. Officials say the terrain made it difficult to position the equipment and as a result they do not expect to begin debris removal until Tuesday.
Tim Monville, the lead investigator with the NTSB, says his investigators documented the site and are trying to piece the plane back together. He says the plane is fragmented and reconstruction could take time.
Monville says most of their investigation into what happened will center around the pilot, the aircraft and the environment.
"Weather is one aspect of many that we look into. The pilot in terms of training and experience and the aircraft - is there any maintenance issue or is there anything that caused this to happen," he said.
Search crews found the wreck site on Saturday afternoon. A helicopter crew spotted a debris trail which led deputies to the crash site on a steep mountain side.
The Campbells' bodies were found among the wreckage of the Cessna 210. Family members said the couple was from Florence, Mississippi and are survived by four children. Calli Campbell's brother told our sister station in Jackson, Miss. that Joseph Allan Campbell was a pilot for Southern Seaplane Inc., based in Belle Chase, La.
On Valentine's Day evening, the couple was en route to Birmingham on approach when air traffic controllers requested them to circle because of inclement weather. By 10:30 p.m., controllers lost contact with the Campbells.
The flight originated from Jackson, Miss. according to NTSB spokesman Peter Knudson.
Jefferson County Commissioner Joe Knight was one of the first people to reach the wreckage. Commissioner Knight says getting to the plane was very difficult since there are several ravines where the plane crashed. He says it looks as though the plane crashed into the side of the mountain.
The cause of the plane crash is still under investigation. The FAA is in the process of collecting any pieces of perishable evidence and then the entire aircraft will be moved to a secure location.
The NTSB expects to release a preliminary report within 10 business days of the date of the crash.
