injurer

One who wounds

One who injures—causes harm, damage, or hurt to another.

The word is straightforward but infrequent, since English usually opts for other constructions: the person who injured him rather than his injurer.

It appears most often in legal or insurance contexts where a term for the responsible party is needed.
