Runaway hero

One

My name is Sammy McStiles. I am 14 years old. My parents are  on the abusive and drunks. I tried to prove that I'm worth the love that I'm not worthless. I woke up this morning to a quiet house. Which is very abnormal to me. I got out of bed, to only trip on my backpack. Leaving me with a gash that is dripping blood. I then slipping on my blood to the bathroom. I do my morning activities then got dressed. I got into a pair of hole infested light wash jeans, a loose baby blue long sleeve shirt, I slipped on my black combat boots and a beanie. I thought that since it's so quiet that maybe they have gone to a bar or something. Boy how I was wrong. I had my bag filled with a couple pairs of cloths and a picture of a happy toddler with her late grandparents. Then there was a knock on the door. With heavy stomping followed. Meaning that they were home but hungover from the night before. Then there was foot steps coming closer to the door.
I grabbed my bag and opened the window. I threw my bag down and jumped out after it. I looked to the front to see cop cars flashing their lights.
I start running only to hear foot steps following behind. I look behind me to see it was a police officer. You may ask why they are chasing me right? Well I may have missed school a lot, and there might of been a disturbance complaint from when I get beat. So either way I don't want to be anywhere near them both. I cut through an ally way, and hopping over thrown trash. I see a ladder up coming so I jumped onto it and started climbing. I rushed up and made it to the roof. I can hear the receding steps going farther down the alley. I take a breathe. I sit on the roof looking at the sky. Watching the clouds and seeing what shape they are formed. I watched the sunset go down to change into the night. I heard a loud scream, which I thought sounded from the alley way below. I looked down to see that a women was on the ground with a group of men surrounding her. I jumped down onto the ladder full on knowing that I need to help her. You may say why did she not fight back against the abuse at home? Well when I try to fight back they will threaten killing my only friend. She lived down the road, she was a sweet old lady that I help out with for pay. But sadly she died last week from a stroke, so I can fight without worry. Okay back to the moment. I run up and tackle a man to the floor. Causing the group to go into shock. I punch the man hard in the temple cause if him to black out. I jump back up and doing that to every single one until one was left. He took out a knife and positioning himself to fight. He ran at me swinging his weapon to swipe me. I took his arm and held it as I kneed him in the gut until he drops the knife. I kick him where the sun don't shine and kneed him in the face until he was unconscious. I took a deep breath, and looked at the frozen women that was looking at the men. I started jogging to the latter and climb up slowly.
'Hey! What's your name?' She asked.
'I mean what name should I tell the police saying you saved me?' She said.
"Call me the runaway." I said and raced back to the roof.
The police showed up at the scene. The police started taking the victims statement. The police is baffled of the person citizen that helped the victim. I got up and ran my bag, then started jumping rooftops. After all I'm just a runaway.
