Someone actually ran numbers on the likelyhood of Kira getting caught in the modern world.
Even if he didn't kill the broadcaster, the deduction of the time periods means the person must be active during certain hours (something I think L mentions), ergo they'd still figure out that he lived in a regional area of Japan. Obviously it'd have taken a lot fucking longer, but if he kept killing people for years on end, then statistically yes, he'd have been caught anyways.
