Russian>English - 1912 Death Record for Piotr Bus - Rybitwy, Poland

Hi All. I am hoping I could get help with a translation of the death of Piotr Bus. I assume it is still Russian in this time period. I am not sure whic time period records in Poland were in Russian. I am hoping this is the father of the immigrant who came through New York in July 1912 on his way to Chicago.
