"he choked victims." This is probably a reference to the way that lions usually kill their prey, by biting its throat. Alternate translation: "he killed his victims" (See: [[rc://en/ta/man/translate/figs-explicit]])
These two phrases are saying the same thing in different ways. The verb may be supplied for the second phrase. Alternate translation: "filled his cave with victims, and filled his dens with torn carcasses" (See: [[rc://en/ta/man/translate/figs-parallelism]] and [[rc://en/ta/man/translate/figs-ellipsis]])
