New Hampshire police say they found a suspected methamphetamine lab in a burning barn in the town of Hill.
One person was injured in the Tuesday afternoon fire.
Hill Police Chief David Kratz says it was immediately apparent the blaze was not a typical structure fire.
He called the Drug Enforcement Agency after investigators found items associated with the production of methamphetamine.
Police say a 30-year-old woman with second-degree burns who was apparently in the barn when the fire started was hospitalized.
No charges have been filed.
The barn and an attached apartment were both destroyed.
