He notices fibers on the victim’s shirt and trousers, so he places both

of these items of clothing in a plastic bag. He also sees fibers on a sheet

near the victim, so he balls up the sheet and places it in a separate

plastic bag. Noticing fibers adhering to the windowsill from which the

attacker gained entrance, Pete carefully removes it with his fingers and

places it in a regular envelope. What mistakes, if any, did Pete make

while collecting this evidence?
