He said this investigation marks the first time the FBI Laboratory and OTD have responded to a “hot air balloon of this nature” and the processing of the corresponding scene. Paul said no “energetic or offensive material” has been detected but emphasized much of the evidence has yet to be recovered.
Asked about the manufacturer of the balloon or whether its design was based on stolen intelligence, Paul said the FBI is not in position “at this point to have that information.” He said both the FBI Laboratory and OTD are working to determine the source of the balloon components. Additionally, the FBI has no information or physical evidence at this time that contradicts previous statements made by other government agencies.
The Laboratory Division leads the collection, transportation, and subsequent forensic examinations of evidentiary material. It is staffed with subject matter experts, including highly trained evidence response dive teams and hazardous evidence response teams, which contribute to the mission of collecting, analyzing, and sharing timely scientific and technical information within the FBI and with other government and law enforcement agencies.
The OTD is the FBI’s provenance for applied technology enabling and enhancing investigations. OTD personnel have been deployed to assist with recovery efforts and initial assessments of technological evidence.
