First of all, it's generally good to post a question in the main topic, beyond the title. Second, Grievous was not killed by spacers. He was killed by General Kenobi in Revenge of the Sith. You may be thinking of the N-K Necrosis, who was introduced and killed off in Star Wars: Galaxies. The "spacers" that killed him are the players of that game, so they currently don't have a set canon identity. -LtNOWIS
Why did you think they were spacers in the first place? Like LtNOWIS said, it was General Kenobi.
