Unrequited Love

What's the deal with the Yale Student? How many suspects do they have now? It's almost like watching a game of Clue. The lab technician, and janitor were questioned. Although the lab technician failed the polygraph test he was still released. He is said to have "unrequited love" for the departed. He is also engaged to someone who works at the same lab. I'm just saying people, somebody committed that horrific crime. A platonic friendship is not easy to maintain, because it often turns into more for one or the other. Be careful with who you share your inner most thoughts with or your next joke may get you...
