I tried to help a 20 ish year old with four stab wounds on his side/stomach.

I was just taking a walk. I missed my bus because the train was late from work. I wanted to just have a fucking walk, easy peasy right? So I took a walk in the city where I live in. I saw him about 50 m ahead. He showed his hands and they where red. The palmes of his hands was bloody. And I knew. I told him that he needed to lay down. He was scared as fuck. Did not want to lay down because he was afriad to be exposed to the same guys who minutes before tried to stab him to death, I guess. I fixed him down to the ground. And saw the stab wounds. There was this dude on the side that was already calling our emergancy number so he was on the phone with the ambulance. I pressed my whole bodyweight on the wounds with my hands. I fixed an tourniquet. It felt that it took forever before the police officer came. He was first on sight and he just kind of crashed his car next to us and runned to the opposite side of the victim and without hesitation he helped me put pressure on the victims wounds. He was the fucking hero. I talked calmly to the dude until the ambulance came. It was obvious that he was known by the police. Why? Because he told me. He had lived a life. He was a kid. And I tried my best to help him. And I can't talk about this.... because people don't understand. I think he survived but I don't know.
