What to do

Hello, on Sunday May 20 I went to my grandma's to help her move out, because she was separating from her boyfriend of 30 years. Also because he was a heavy drunk. When my father and I arrived at the house we found out that my grandma's boyfriend almost committed suicide. My uncle notice the gun when he was trying to hide it, and he eventually confiscated the gun. I had no idea how to react to this, but my father knew what to do, first he checked if the gun was loaded (it was) then he called the cops, because at the time we did not know really what he was going to do with it we only assumed. The cops arrived and lots of questioning went on and then the cops found 2 more guns and confiscated them. My grandma was devastated her face was one of horror and "can this really be happening". In the end though i saw someone who I thought I knew get carried out of the house in hand cuffs. He was not charged with anything because he had the gun on the floor, but even then he does not want the guns the cops confiscated. Also, he was allowed to return to his home that day, but my grandma no longer lives there right now, she is now living with  one of my uncles. In this whole situation I did not know what to do. As much as I do love him i could no longer look him in the face and in two days he will move and be gone forever.
