The Encrypted Massacre Investigation

"About two years ago, criminals well known in Japan began strangely dying off in large numbers. All from heart attacks. As Lawliet, the otiginal "L", investigated, he discovered a high school boy named Light Yagami. He was very egotistical and seemed to judge everyone within justa few seconds of meeting them. As the investigation continued, all signs pointed to Light Yagami as the killer, or Kira, as he was called. We only knew that Kira needed a name and face to kill, but we were unable to distinguish how he was killing them. He could control the victims before they died, and even specify the cause of death. We were unaware of the source of his power until a notebook was found, containing names of all of the deceased criminals. There was another Kira by the name of Misa Amane who also helped Light with the murders, but she was only barely crucial. Anyway, There was originally a task force led by L to catch the killer, consisting of a small group of local police detectives. Light's father was one of them. After light was caught as kira, he died susseny by a heart attack, supposedly killed by a Shinigami (god of death). Strange, yes, but no stranger than this new case."
L explains roughly and stands up, walking to the console, slowly as if afraid he might fall. (for those of you who may be confused at this, Near, the new L, can't walk very well.) He picks up the manilla folder and sits back down, handing it to you. "Go ahead and open it up." You lift the envelope's flap. and pull out a few sheets of paper and some pictures of a guesome murder scene. L points to one of them. The late thirty-year-old man was lying across a sofa, blood stained around a long slash down his back.
