Once Upon Summerville

Kimberley, she's the woman of a man's dream. Pretty and smart, perfect in every way. She thought she's going to have a fairytale ending with the love of her life, Chad. She did, just for a little while. Until Chad was found dead in their house. Who is the killer? Is it Craig? Chad's twin brother who had been in love with Kim long before Kim and Chad even barely know each other? Or is it Angie? Kim's older sister who is also in love with Chad since forever? Or maybe it's April, whom Craig had several one night stands with? Could it be Aunt Chelsea, who had took care of both Angie and Kim since they were still young? Could it be someone else? Or is it Kim actually who killed Chad? If so, why?
