When the local PD announces on FB that they found a backpack and to visit their office to claim it... so you show up to get back the drugs you had lost.
The posting in the link said the person claimed the backpack and all of its contents as his own....I suppose it is possible to claim that someone put their stuff in the pack after you lost it. Not that I'd want to go through all that hassle to avoid buying another pack.
Cops in California will try and get the drugs back if victim has a witness, a license # and good description of thief. Otherwise cops turn the case over to human services and welfare office so they can give victim extra commodity stamps they can sell to offset the lose.Then there are the idiots calling the cops telling them that someone ripped them off and stole their drugs.
