Stated in the title, I am currently house sitting my Mother and Step-Dad's house. They are out of town till Friday. My sister and her boyfriend stopped by unannounced about an hour ago. I locked all the doors and turned off all the lights. Both of them have been in prison before. I, nor any of my family has met her boyfriend. He is not allowed in the house because he is most likely a druggie. I called my mom and my brother, I told them the deal and they are sure they were here to try and steal some stuff. When my sister called me I told her I was out. They tried to get into the house for about a good 10-15 minutes. On the phone she asked if there was anyway to get into the house, she said that she "forgot to bring her key". She isn't ment to be here if no one is here, and I do not want them in here. She might stop by later with a key and try to get in. She won't be able to get in because I have the extra lock set. At that time they will know I am here. 

Oh yeah I'm 20 and my dad is a retired cop. My dad does not like my sister. I must mention that she is my half sister. We do not have the same dads. 

More info. My sister told my mom that she didn't have any money to go anywhere. No gas money. She drove about 30+ miles to get here.

So should I be worried that they might come back later to try and get in the house again?
