My question involves criminal law for the state of: Texas
I am feeling extremely guilty and idiot already, so I'd really appreciate it if you hold the comment about how stupid I am or my stupid action.
I'm 20, never do anything wrong, and have never dealt with any legal stuff. What happened was, money was a little tight for me, and I got caught shoplifting at Walmart (Houston) for 2 items, less than $15 in total. I was caught by 2 of their Loss Prevention Officer, and escorted to their back room. Once in the room, they took my license (return it afterwards), SS number, and picture. Because it was less than $25, they told me to expect a letter for the fine and escorted me out of their premise. I was firmly told to make sure I look for that letter and pay it. Or even better, call the number after 4-5 days to avoid the letter be missing and be fined for both the incident and interest on it. There was no police involved and they said I'm not banned from the store, but police will be involved if this happen again in the future (which I will never ever ever do again). I will call the number they provided in a few days, and hoping to not have this show up on my record. I really want a clean closure on this embarrassing incident.
My questions are:
1) Will this be on my permanent record?
2) Will it still be on the record if I pay the fine?
3) How much should I be expecting the fine to be? Google seems to say expect around $400, would that be true?
4) Can this bring more problem in the future, even if I were to pay the fine in full?
5) If I were to look for a job, will this show up in my background check?
6) Is there any way I can erase this from the record?
I've learned my lesson, and thank you for the help in advance.
