the stalking skinwalker

I was in the woods playing with 2 of my friends that were having a sleep party with me. We saw some awesome stones we wanted but decided to go get them in the night, because my parents don't want us to bring anything back home. When we came back one of the stones had dissapeared. We decided to go look for it And split up. After a few minutes I heard a lot of crows screeching. I decided to head back. Me and Mason got back but we didn't see Jim. We called his name "JIM, JIM!"  He answered back but in a raspy voice. "Where did you guys go!" We are with the stones!  I yelled. Come back! We didn't get an answer. After 2 minutes we decided to go in the direction where we last heard his voice. We saw what i think was his arm behind the tree. I ran to the tree grabbed the arm and yelled. "Here you are!" That's when I noticed, it was only an arm. I screamed at the top of my lungs. "WHAT THE FUCK!" Me and Mason ran away as fast as we could. I've never in my life ran faster. We got back to the house were my parents were already standing outside looking worried. "Where is Jim!" My mom yelled. "i don't know, we were collecting stones and we split up because one of them was missing, we couldn't find Jim and then found his arm." I cried. Mason was to scared to even say a word when suddenly we saw Jim walking back. I was hesitant to run towards him but Mason was already running. "Jim, I thought you died!" He yelled. My mom yelled. "Get back Mason, that is not Jim!" What we thought was Jim suddenly  transformed in a 8 foot tall creature with a deerskull as head, dark but yellow eyes, claws sharper than a knife and skinny, very skinny. It picked Mason up and just pushed his claws right through Masons stomach. my mother grabbed me and pulled me in the house. My father locked the door and grabbed his shotgun hanging on the wall. My mom ran upstairs with me and pushed me in my closet she said to not come out ever, until she opened the closet. She closed the door and that is when I heard the shotgun go off, once, twice and then a third time. My mom screamed and suddenly it was quiet. Then my mom yelled in a sweet voice. "Jasper, it's safe you can come out now" I stood up in the closet, just when I was about to open the closet door I remembered what my mom said. "Don't come out until I open the door." So, i sat back down and waited, Then I waited some more. After what I think were 5 hours I got out the closet I went downstairs and saw my dead parents, or what was left of them atleast. I snuck to the front door and as soon as I was out of the house i started running. I didn't stop running and I never looked behind me. I was to scared. Now 11 years later, I am 27 and almost forgot the incident. That was until, I heard my mom whispering, in that same sweet voice again.
"I found you."
