Deaht Notice and Item-health

Hello guys, I have searched a lot everywhere and didn’t found so i’ve come here. I have two things I couldn’t find : the basic Death Notice of DarkRP and the Item_health of Half-Life 2 because I want to modify it on my Garry’s Mod server. So if you know the directory of them could you please share it with me ? thanks a lot
