Nor should they. This is a matter for local police and regulatory enforcement staff. If the local district's enforcement forces are too feeble to handle the workload, then they should be beefed up until they can handle it.
If someone uses a kitchen knife to murder another human, the manufacturer of that knife is under no obligation to assist in any way with the investigation of that crime and the prosecution of the murderer. This is right and proper. This ever-intensifying cry to press private companies into service as investigative and police forces (rather than properly staffing and funding the relevant governmental offices) is deeply disturbing.
