Do you keep spoons with flame discoloration and syringes and maybe some surgical tubing in your house? That would be my guess as to what they found.
syringes with residue - otherwise you were pretty much spot on. Oh, a mirror and a straw to snort with (not long enough for use in a beverage). Best part is, all conveniently packed in a small bag along with a little baggy with residue.
I don't know what follow up the OP was looking for? I'm sure they will have their day in court, maybe a trip to the ER or Baltimore (coroner)
Oops, just saw that all that was pretty much caught earlier
But to the comment about it being "everyday" items, no. The straw used is thicker that a stir stick and much shorter than a beverage straw. If they are smoking it's not a standard pipe - no, it's a glass pipe - which by the way are legal to sell but tobacco smokers don't use them - go figure.
