"Tell me Captain. Were there any mysterious deaths by heart attack that occured to otherwise healthy individuals before these four murders were committed?"
"No, no, that's too easy,"He began off-handedly, talking to himself,"A new tool such as the Death Note you don't just go and use on someone you don't like in your life, too permanent a solution. Besides that fact, there's over a hundred people that die everyday, too much to track, do it on someone no one would miss if you're trying it out. Narrowing it down requires more than just freak heart attacks, too easy to miss on our part, wastes resources. Hmmm....not even certain a Death Note was involved, we're stuck on speculation right now, patterns emerge as time goes on, all that's known is that a cycle similar to Kira's has started."
The steady repetitiveness of his cane thumping against the floor stopped and Undertaker stood there, staring at the floor.
"No, red ink too hard to track, too far-reaching, cast a net with fewer holes, hmmm...Kira, Death Note, prisoners, what can we all surmise...too many prisons and prisoners to track if he concentrates on them...less holes, more fish caught, what do we take? We need all the information, not just the deaths, what they were tied to, first link is media exposure, what are the next ones? No, too simple, something else,three small time, one big wig, more information is needed if you have anyth-"
He stopped mid-sentence,"Something more needs to be there, we're just not seeing it right now. What could....it....be? This isn't a serial, a Kira is something more, random killings are done, we need their sheets, anything that connects them is needed, cross-reference with Cho Sato. Random busts, underling mingle-lings, anything. Too little to do anything with, patterns, patterns, anything we can find."
