Oscar

You live in a small town, and it's October 31st, Halloween. All the houses are decorated, skeletons hang from the trees, but mysterious murders, recorded on video, have begun to occur throughout the town. Before their death, the victim would find the body of a dog, and then a man in a black robe, leather gloves, and a silicone skull mask would kill the victim. This man had already killed your sister, and you wanted revenge. You found out who the killer was and spent a long time developing a plan to get revenge. A friend of yours was working as a babysitter for a police officer, looking after his son, and one day she became ill. So she asked you to babysit him, and you agreed. You arrived and went into the house. In the living room, you saw the police officer's son, Cassidy. You talked to him, played hide-and-seek, and then put him to bed. You started noticing strange things in the house, and then, when you went outside to check on what was going on, you found the dog's body. You realized everything was going according to plan. With the help of a friend, you sent Cassidy to a friend's house while you waited for the killer. Later, you heard a window break on the second floor, and you were absolutely sure he was in the house. You recorded yourself calling the police. He heard the recording and came downstairs. He came into the kitchen and didn't see you there, only the recorder with the recording. He stood there, realizing you'd fooled him. At that moment, he turned around, and at that very moment, you swooped down on him with a taser. Later, he woke up tied to a chair, and you were standing next to him with a camera, filming him just as he had done. You held a knife in your hand and said, "I know you killed my sister and other innocent people." You removed his mask and saw the face of one of the police officers, who turned out to be the killer, something you knew all along but couldn't prove to anyone. His name was Oscar.
