I was caught shoplifting at walmart, as i was leaving, an LP stopped me at the door, told me the items in my purse needed to be returned, and i should go back inside with him. i complied, without resisting and went into the back of the store with him. I allowed him to empty my purse in which he found 35.00 worth of merchandise. He did not call the police, but asked me a series of questions about myself. address, phone number, age height weight, he asked if i had a drivers license, to which i answered yes, and i believe he wrote down my drivers license number. i was not asked to sign anything, he then told me i should expect a court summons in the mail, and a letter from walmart. today i received a civil demand letter, should i pay it? if i dont will they decide to file criminal charges?
