Types of Biological Evidence (AFAIK they said they had "biological evidence".)
Immediately when I heard this I thought of No. 5 ....
Iirc, law enforcement has never said any such thing as "biological". Perhaps somebody could correct us with a link! :moo: They reported finding evidence which is at Laboratories, but that could even be the phone evidence sent to FBI laboratories?
