According to the report, he's apparently alive.
Literal
Report [according-to-によれば] he [topic-は] is-alive [hearsay-そうだ]
によれば = 'according to' (に + よる 'to depend on' + ば conditional). そうだ at sentence end marks hearsay — 'reportedly.' This is the hearsay そうだ (plain form + そうだ), distinct from the appearance そう (verb stem + そう = 'looks like'). The two markers together — source citation + hearsay — are a natural Japanese way to attribute information.
