I live in SC. Yesterday my husband found a thin wallet in the bed of his pickup truck. Inside the wallet was a SC license, SC issued Private Investigator ID and his credit cards. He was obviously in the bed of the truck snooping around and dropped his wallet. Are PI's allowed to be inside of or mess with your property, legally speaking? I thought PI 101 was don't leave behind evidence. I'm not sure who put this PI up to this or why we have been watched, but I don't appreciate feeling like my property has been tampered with. We have also found a few strange occurrences within our apartment over the last couple of months, such as my husband's work laptop being moved from his work bag to another locating in the apartment. We also found a pile of small rocks that were taken from outside our front door and left in a small pile in the middle of our home office. My husband was bad about leaving the back door locked so I wouldn't doubt that someone could have been in our apartment. With the finding of this wallet and PI card, it's starting to make sense, but I don't have concrete proof that he was in my apartment, however, I do know he was in the bed of my husband's pick up truck. Can anyone shine some light on what is acceptable for a PI to do or NOT do. Thanks.
