The Houston County Sheriff's Office say they're investigating the possibility two recent bomb threats are related.

Last Friday morning a man called the Court Clerk's office claiming there was a bomb in the Houston County Courthouse. The building was evacuated and searched-- but nothing was found.

Then Monday afternoon a similar situation-- only this time the call was made to Dothan Police. Again, nothing was found.

Deputies say the back to back threats are suspicious and could be related. They're working to trace the source of the felony hoaxes.
