Wow, good work, but there was no Rotom involved, only the people in the hotel, which were Sceptile, Zangoose, Dusclops, Haxorus etc. etc.
The police told you that Sceptile had been cooked alive and dragged down the hallway, according to them, there was Sceptiles blood trail leading from his room to the location he was found. The police, however, denied you access to his room; there aparantly was extremely high radiation levels in the room, so it was closed for inspection by a team of Rotoms, which can withstand radiation.
Key Facts:
• Sceptile kept no grudges
• Sceptile had some feud with Charmeleon recently
• Sceptile knew something about the murder everyone else didnt
• He sometimes sleepwalked
