In the Battle Royale based RP Survival of the Fittest, characters are often killed off in this manner, particularly inactive ones. A good example would be the death of Joe Cande, who passed out shortly before his handler became inactive; He was killed by a bullet that hit him in the neck when it ricocheted off of a weapon being held by someone else.
Subverted with the escape attempts in v3 and v4. Both examples made it look like a mass bridge-dropping at first, until further updates revealed that they weren't dead. In v3 it turned out that they had all removed their collars and were fighting to get off the island, and in v4 the escapees were revealed to have successfully left the island and were now in a hospital in Canada.
In the lonelygirl15 story "Prom: It's To Die For", Gina Hart was shot by Edward Salinas, so that he could be promoted to Elder. Then, a week later in "Hangman's Noose", Salinas was killed off.
As of Episode 38 of Shadow of Israphel, Knight_Peculier has seemingly gone this way, having fallen into a pool of radioactive waste, much to Lewis Brindley and Simon Lane's horror. One reckons the writers did this deliberately, as opposed to the accidental death of Um_Bongo (who has had an Unexplained Recovery for the survival maps and mod spotlights).
In We Are All Pokémon Trainers, upon finding a treasure room which turned out to be Larva and Metentis' summer house, Brudy was abruptly eaten by Larva the Cofagrigus after Metentis the Dusclops told her she couldn't have any servants.
