In addition to the comment of Ryoko-san（It should be written on the answers box）, I'd like to say below. When the affair is new, we say "Tanaka-san ga shinda/shinimashita! （Hei! Mr.Tanaka died!）"

You are welcome. どういたしまして。(*有難うございまう --> 有難うございます。)

有難うございまう 皆さん

We say "(someone/subject) wa shinimashita" (with the formal form) or "(someone/subject) wa shinda (with the informal form). *We use the particle は after the subject and it's pronounced わ.
