It would somewhat depend on the circumstances.
Let's say, for example, the police come into possession of that part. If it forms the subject matter of a criminal case and is seized as evidence, there are existing provisions in the code that deal with the disposal of those things that serve as evidence in a file. Forfeiture and disposal are, I think, what you're alluding to.
Again, unless you have a particular set of circumstances in mind.... I could try to answer, but, as an example, that's how things seized for an evidentiary purpose are eventually disposed of.
