Update Tuesday

Authorities have determined the explosion that killed one and injured another at a home in Wilson County at around 5 p.m. Monday came from a delivered package.

The home the explosion occurred is at 580 Vance Lane off Hartsville Pike in eastern Wilson County.

Investigators with the Bureau of Alcohol, Tobacco, Firearms and Explosives are continuing to collect evidence at the scene today, according to Special Agent Michael P. Knight. They will also be interviewing neighbors and doing testing to learn more about what caused the explosion. Multiple agencies are participating in the investigation.

The ATF has ruled out accidental causes, but a motive remains unknown.

"We do believe that this is an isolated incident," he said.

The home was near Wilson County's McClain Christian Academy, which relocated its main campus Tuesday to First Presbyterian Church in Lebanon because of the explosion.

The private school campus, about 100 to 150 yards from the home, was not damaged by the explosion authorities are still investigating.

"We felt it would be best to open that area up for the investigation; we want to keep down unneccesary traffic," McClain Christian headmaster Joel Walsh said.

The main campus is for pre-kindergarten through eighth grade. The high school grades regularly meet at Cumberland University. The main campus opened two hours late.

Officials will evaluate when to return to the campus.
