One of my wifes friends lost her father the same way. He was dying from cancer and wanted to enjoy some turkey hunting while he still could get into the woods. A trespasser (poacher) on the property saw some movement and shot into the brush hitting him with buckshot.
They all say he died doing what he loved (minus the being shot) and the guy was caught and brought up on manslaughter, trespassing and whatever else.
Really makes you think, I hope to take my 5 yr old son with me some for turkey and deer.
