<human>: She has a really close friend [20M] who recently got drunk and assaulted an acquaintance of mine by hitting him on the head with an iron rod causing him severe injury. He managed to get away with it thanks to some influential connections and what not but he lied to her by saying that he was just at the scene and wasn't the one who actually assaulted the other guy but a third person did. Today I found out that it was actually him and that the third person had just provoked the incident. Really don't know what to do because she is very close to this friend and he and I have loads of mutual friends.

Give me a shortened version of the text
